106ContextLactic AcidemiaIncreased lactic acid concentrations in urine or serum can be a result of many metabolic disorders but also of other origin (infections, etc.). Respiratory chain defects account for most of the metabolic causes of lactic acid accumulation. Often alanine is also high. A urine spectrum indicating an increased lactic acid and alanine concentration is shown.DiseasePW000114CenterPathwayVisualizationContext11424002200#000099PathwayVisualization13Alanine MetabolismAlanine (L-Alanine) is an α-amino acid that is used for protein biosynthesis. Approximately 8% of human proteins have alanine in their structures. The reductive lamination of pyruvate is effected by alanine transaminase. L-Alanine can be converted to pyruvic acid by alanine aminotransferase 1 reversibly coupled with interconversion of oxoglutaric acid and L-glutamic acid. L-Alanine can also be produced by alanine-glyoxylate transaminase with coupled interconversion of glyoxylate and glycine. L-Alanine will be coupled with alanyl tRNA by alanyl-tRNA synthetase to perform protein biosynthesis. Alanine can also be used to provide energy under fasting conditions. There are two pathways that can facilitate this: (1) alanine is converted to pyruvate to synthesize glucose via the gluconeogenesis pathway in liver tissue or (2) alanine converted into pyruvate moves into the TCA cycle to be oxidized in other tissues.Metabolic111SubPathway332105Compound222SubPathway2148Compound3129Lehninger, A.L.

triphosphateHMDB0000538Adenosine triphosphate (ATP) is a nucleotide consisting of a purine base (adenine) attached to the first carbon atom of ribose (a pentose sugar). Three phosphate groups are esterified at the fifth carbon atom of the ribose. ATP is incorporated into nucleic acids by polymerases in the processes of DNA replication and transcription. ATP contributes to cellular energy charge and participates in overall energy balance, maintaining cellular homeostasis. ATP can act as an extracellular signaling molecule via interactions with specific purinergic receptors to mediate a wide variety of processes as diverse as neurotransmission, inflammation, apoptosis, and bone remodelling. Extracellular ATP and its metabolite adenosine have also been shown to exert a variety of effects on nearly every cell type in human skin, and ATP seems to play a direct role in triggering skin inflammatory, regenerative, and fibrotic responses to mechanical injury, an indirect role in melanocyte proliferation and apoptosis, and a complex role in Langerhans cell-directed adaptive immunity. During exercise, intracellular homeostasis depends on the matching of adenosine triphosphate (ATP) supply and ATP demand. Metabolites play a useful role in communicating the extent of ATP demand to the metabolic supply pathways. Effects as different as proliferation or differentiation, chemotaxis, release of cytokines or lysosomal constituents, and generation of reactive oxygen or nitrogen species are elicited upon stimulation of blood cells with extracellular ATP. The increased concentration of adenosine triphosphate (ATP) in erythrocytes from patients with chronic renal failure (CRF) has been observed in many studies but the mechanism leading to these abnormalities still is controversial.

It is highly concentrated in muscle and is one of the most important amino acids released by muscle, functioning as a major energy source. Plasma alanine is often decreased when the BCAA (branched-chain amino acids) are deficient. This finding may relate to muscle metabolism. Alanine is highly concentrated in meat products and other high-protein foods like wheat germ and cottage cheese. Alanine is an important participant as well as a regulator of glucose metabolism. Alanine levels parallel blood sugar levels in both diabetes and hypoglycemia, and alanine reduces both severe hypoglycemia and the ketosis of diabetes. It is an important amino acid for lymphocyte reproduction and immunity. Alanine therapy has helped dissolve kidney stones in experimental animals. Normal alanine metabolism, like that of other amino acids, is highly dependent upon enzymes that contain vitamin B6. Alanine, like GABA, taurine, and glycine, is an inhibitory neurotransmitter in the brain (http://www.dcnutrition.com/AminoAcids/). L-Alanine has been found to be associated with glucagon deficiency, which is an inborn error of metabolism.56-41-7C00041595016977L-ALPHA-ALANINE5735DB00160C[C@H](N)C(O)=OC3H7NO2InChI=1S/C3H7NO2/c1-2(4)3(5)6/h2H,4H2,1H3,(H,5,6)/t2-/m0/s1QNAYBMKLOCPYGJ-REOHCLBHSA-N(2S)-2-aminopropanoic acid89.093289.0476784730.702L-alanine00FDB000556(2s)-2-aminopropanoate;(2s)-2-aminopropanoic acid;(s)-(+)-alanine;(s)-2-aminopropanoate;(s)-2-aminopropanoic acid;(s)-2-amino-propanoate;(s)-2-amino-propanoic acid;(s)-alanine;2-aminopropanoate;2-aminopropanoic acid;2-aminopropionate;2-aminopropionic acid;2-ammoniopropanoate;2-ammoniopropanoic acid;Ala;Alanine;L-(+)-alanine;L-2-aminopropanoate;L-2-aminopropanoic acid;L-2-aminopropionate;L-2-aminopropionic acid;L-a-alanine;L-a-aminopropionate;L-a-aminopropionic acid;L-alpha-alanine;L-alpha-aminopropionate;L-alpha-aminopropionic acid;A-alanine;A-aminopropionate;A-aminopropionic acid;Alpha-alanine;Alpha-aminopropanoate;Alpha-aminopropanoic acid;Alpha-aminopropionate;Alpha-aminopropionic acid;A;L-alanin;L-α-alaninePW_C000105Ala10229431681446501453511454263022153439354071175418103543111854521205557132557813356371075638108588310565298583502251227115112620311262718152302224245232042453318425343157796934677975327779883267800811178092112791651148069313511991012212001512412002640612114542312115142412116441612122040912213940712371745812372345912373645212379013712469111912530029712539329912540447912629648112685020512693338812694450112786020632Adenosine monophosphateHMDB0000045Adenosine monophosphate, also known as 5'-adenylic acid and abbreviated AMP, is a nucleotide that is found in RNA. It is an ester of phosphoric acid with the nucleoside adenosine. AMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase adenine. AMP can be produced during ATP synthesis by the enzyme adenylate kinase. AMP has recently been approved as a 'Bitter Blocker' additive to foodstuffs. When AMP is added to bitter foods or foods with a bitter aftertaste it makes them seem 'sweeter'. This potentially makes lower calorie food products more palatable.61-19-8C00020608316027AMP5858DB00131NC1=C2N=CN([C@@H]3O[C@H](COP(O)(O)=O)[C@@H](O)[C@H]3O)C2=NC=N1C10H14N5O7PInChI=1S/C10H14N5O7P/c11-8-5-9(13-2-12-8)15(3-14-5)10-7(17)6(16)4(22-10)1-21-23(18,19)20/h2-4,6-7,10,16-17H,1H2,(H2,11,12,13)(H2,18,19,20)/t4-,6-,7-,10-/m1/s1UDMBCSSLTHHNCD-KQYNXXCUSA-N{[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}phosphonic acid347.2212347.063084339-2.025adenylate0-2DBMET00485FDB0218065'-amp;5'-adenosine monophosphate;5'-adenylate;5'-adenylic acid;Amp;Adenosine 5'-monophosphate;Adenosine 5'-phosphate;Adenosine 5'-phosphorate;Adenosine 5'-phosphoric acid;Adenosine phosphate;Adenosine-5'-monophosphorate;Adenosine-5'-monophosphoric acid;Adenosine-5-monophosphorate;Adenosine-5-monophosphoric acid;Adenosine-monophosphate;Adenosine-phosphate;Adenovite;Adenylate;Adenylic acid;Cardiomone;Lycedan;Muscle adenylate;Muscle adenylic acid;My-b-den;My-beta-den;Phosaden;Phosphaden;Phosphentaside;5'-o-phosphonoadenosine;Adenosine 5'-(dihydrogen phosphate);Adenosine monophosphate;Adenosine-5'p;Adenosini phosphas;Ado5'p;Fosfato de adenosina;Pa;Pado;Phosphate d'adenosine;5'-adenosine monophosphoric acid;Adenosine phosphoric acid;Adenosine 5'-(dihydrogen phosphoric acid);Adenosine 5'-monophosphoric acid;Adenosine monophosphoric acid;Adenosine-5'-monophosphate;Phosphoric acid d'adenosinePW_C000032AMP112344628270167343288122118914457254867545033895251104540811754231035432118545712055581325583133577910157951086977199707218811789198118681611198815112003222125802261263631126942901333122542266342646315772343297732511178392334788091157932011280399180684135809007119916122120016124120031406120246382120888405121954408122920399123464376124507374125306297125394299125409479125596484126853205126934388126949501127124389127311209127711502140771891170PyrophosphateHMDB0000250The anion, the salts, and the esters of pyrophosphoric acid are called pyrophosphates. The pyrophosphate anion is abbreviated PPi and is formed by the hydrolysis of ATP into AMP in cells. This hydrolysis is called pyrophosphorolysis. The pyrophosphate anion has the structure P2O74-, and is an acid anhydride of phosphate. It is unstable in aqueous solution and rapidly hydrolyzes into inorganic phosphate. Pyrophosphate is an osteotoxin (arrests bone development) and an arthritogen (promotes arthritis). It is also a metabotoxin (an endogenously produced metabolite that causes adverse health affects at chronically high levels). Chronically high levels of pyrophosphate are associated with hypophosphatasia. Hypophosphatasia (also called deficiency of alkaline phosphatase or phosphoethanolaminuria) is a rare, and sometimes fatal, metabolic bone disease. Hypophosphatasia is associated with a molecular defect in the gene encoding tissue non-specific alkaline phosphatase (TNSALP). TNSALP is an enzyme that is tethered to the outer surface of osteoblasts and chondrocytes. TNSALP hydrolyzes several substances, including inorganic pyrophosphate (PPi) and pyridoxal 5'-phosphate (PLP), a major form of vitamin B6. When TSNALP is low, inorganic pyrophosphate (PPi) accumulates outside of cells and inhibits the formation of hydroxyapatite, one of the main components of bone, causing rickets in infants and children and osteomalacia (soft bones) in adults. Vitamin B6 must be dephosphorylated by TNSALP before it can cross the cell membrane. Vitamin B6 deficiency in the brain impairs synthesis of neurotransmitters which can cause seizures. In some cases, a build-up of calcium pyrophosphate dihydrate crystals in the joints can cause pseudogout.14000-31-8C0001364410218361PPI559142DB04160OP(O)(=O)OP(O)(O)=OH4O7P2InChI=1S/H4O7P2/c1-8(2,3)7-9(4,5)6/h(H2,1,2,3)(H2,4,5,6)XPPKVPWEQAFLFU-UHFFFAOYSA-N(phosphonooxy)phosphonic acid177.9751177.9432255064pyrophosphoric acid0-3FDB021918(4-)diphosphoric acid ion;(p2o74-)diphosphate;Diphosphate;Diphosphoric acid;Ppi;Pyrometaphosphate;Pyrophosphate;Pyrophosphate tetraanion;Pyrophosphate(4-) ion;[o3popo3](4-);Diphosphat;P2o7(4-);Pyrophosphat;Pyrophosphate ion;Phosphonato phosphoric acid;Pyrophosphoric acid;Pyrophosphoric acid ionPW_C000170Ppi1223546384292373532882221217316204924105928152941751448685450348952521045294101540911754241035433118545812055481115559132558413356061355655108587910762391666978199707318871341637272160731219873182138275151828321011869161120022221204116412315225123232491251228812579226126952901521930615375183476017425613154269731877235329773171287763533678416335789283317915311279950134799581308004737280417170856301947863849481412594819382986782231106343911132703951132753891155271361155323991199341221200171241200324061203304101209364071212614291213411211214863831224074221229854441235021191238314641240443981249773751253242971253952991254104791255974841256564851258764811265524911268692051269353881269505011273372061281245081407728911005Zinc (II) ionHMDB0001303Zinc is an essential element, necessary for sustaining all life.Physiologically, it exists as an ion in the body. It is estimated that 3000 of the hundreds of thousands of proteins in the human body contain zinc prosthetic groups. In addition, there are over a dozen types of cells in the human body that secrete zinc ions, and the roles of these secreted zinc signals in medicine and health are now being actively studied. Intriguingly, brain cells in the mammalian forebrain are one type of cell that secretes zinc, along with its other neuronal messenger substances. Cells in the salivary gland, prostate, immune system and intestine are other types that secrete zinc. Obtaining a sufficient zinc intake during pregnancy and in young children is a problem, especially among those who cannot afford a good and varied diet. Brain development is stunted by zinc deficiency in utero and in youth. Zinc is an activator of certain enzymes, such as carbonic anhydrase. Carbonic anhydrase is important in the transport of carbon dioxide in vertebrate blood. Even though zinc is an essential requirement for a healthy body, too much zinc can be harmful. Excessive absorption of zinc can also suppress copper and iron absorption. The free zinc ion in solution is highly toxic to plants, invertebrates, and even vertebrate fish. The Free Ion Activity Model (FIAM) is well-established in the literature, and shows that just micromolar amounts of the free ion kills some organisms.23713-49-7C000383205129105ZN%2b229723DB01593[Zn++]ZnInChI=1S/Zn/q+2PTFCDOFLOPIGGS-UHFFFAOYSA-Nzinc(2+) ion65.40963.9291465780zinc(2+) ion22FDB003729Zinc;Zinc ion;Dietary zinc;Zinc cation;Zinc, ion (zn2+);Zn(ii);Zn(2+);Zn2+PW_C001005Zinc13238411882711652915295751304468312029314770541011754251035434118545912055601325585133559813574491661178719812466226127242901332115176967225774011117758011477929336804001120020124120035406120060122120441409121257429123075137123827464125398299125413479125438297125685483126938388126953501126976205127180208134Oxoglutaric acidHMDB0000208Oxoglutaric acid, also known as alpha-ketoglutarate, alpha-ketoglutaric acid, AKG, or 2-oxoglutaric acid, is classified as a gamma-keto acid or a gamma-keto acid derivative. gamma-Keto acids are organic compounds containing an aldehyde substituted with a keto group on the C4 carbon atom. alpha-Ketoglutarate is considered to be soluble (in water) and acidic. alpha-Ketoglutarate is a key molecule in the TCA cycle, playing a fundamental role in determining the overall rate of this important metabolic process (PMID: 26759695). In the TCA cycle, AKG is decarboxylated to succinyl-CoA and carbon dioxide by AKG dehydrogenase, which functions as a key control point of the TCA cycle. Additionally, AKG can be generated from isocitrate by oxidative decarboxylation catalyzed by the enzyme known as isocitrate dehydrogenase (IDH). In addition to these routes of production, AKG can be produced from glutamate by oxidative deamination via glutamate dehydrogenase, and as a product of pyridoxal phosphate-dependent transamination reactions (mediated by branched-chain amino acid transaminases) in which glutamate is a common amino donor. AKG is a nitrogen scavenger and a source of glutamate and glutamine that stimulates protein synthesis and inhibits protein degradation in muscles. In particular, AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in skeletal muscles (PMID: 26759695). Interestingly, enteric feeding of AKG supplements can significantly increase circulating plasma levels of hormones such as insulin, growth hormone, and insulin-like growth factor-1 (PMID: 26759695). It has recently been shown that AKG can extend the lifespan of adult C. elegans by inhibiting ATP synthase and TOR (PMID: 24828042). In combination with molecular oxygen, alpha-ketoglutarate is required for the hydroxylation of proline to hydroxyproline in the production of type I collagen. A recent study has shown that alpha-ketoglutarate promotes TH1 differentiation along with the depletion of glutamine thereby favouring Treg (regulatory T-cell) differentiation (PMID: 26420908). alpha-Ketoglutarate has been found to be associated with fumarase deficiency, 2-ketoglutarate dehydrogenase complex deficiency, and D-2-hydroxyglutaric aciduria, which are all inborn errors of metabolism (PMID: 8338207).328-50-7C0002651309152-KETOGLUTARATE50DB02926OC(=O)CCC(=O)C(O)=OC5H6O5InChI=1S/C5H6O5/c6-3(5(9)10)1-2-4(7)8/h1-2H2,(H,7,8)(H,9,10)KPGXRSRHYNQIFN-UHFFFAOYSA-N2-oxopentanedioic acid146.0981146.021523302-0.442oxoglutarate0-2FDB0033612-ketoglutarate;2-ketoglutaric acid;2-oxo-1,5-pentanedioate;2-oxo-1,5-pentanedioic acid;2-oxoglutarate;2-oxoglutaric acid;2-oxopentanedioate;2-oxopentanedioic acid;Oxoglutarate;Alpha-ketoglutaric acid;Oxoglutaric acid;A-ketoglutarate;A-ketoglutaric acid;Alpha-ketoglutarate;α-ketoglutarate;α-ketoglutaric acidPW_C000134AKG152423141414684991867331110842126351447501455261467545375103541411754381185564132600814760361556069157609216164821786530857471222751522475191518209225837422011863198126812897705425377135133774811117752311277746129779673457797034677976327779843477842533480018368806941351131629411997240612002212412008440712017412212055241412081441812098940812114642312115242412116042512275712012283111912318645012339945412355437412371845812372445912373246012535747912540029912545548112553329712580048912592948212690050112694038812699320612706620512725550612738850295L-Glutamic acidHMDB0000148Glutamic acid (Glu), also referred to as glutamate (the anion), is one of the 20 proteinogenic amino acids. It is not among the essential amino acids. Glutamate is a key molecule in cellular metabolism. In humans, dietary proteins are broken down by digestion into amino acids, which serves as metabolic fuel or other functional roles in the body. Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, it is believed that glutamic acid is involved in cognitive functions like learning and memory in the brain. Glutamate transporters are found in neuronal and glial membranes. They rapidly remove glutamate from the extracellular space. In brain injury or disease, they can work in reverse and excess glutamate can accumulate outside cells. This process causes calcium ions to enter cells via NMDA receptor channels, leading to neuronal damage and eventual cell death, and is called excitotoxicity. The mechanisms of cell death include: * Damage to mitochondria from excessively high intracellular Ca2+. * Glu/Ca2+-mediated promotion of transcription factors for pro-apoptotic genes, or downregulation of transcription factors for anti-apoptotic genes. Excitotoxicity due to glutamate occurs as part of the ischemic cascade and is associated with stroke and diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimer's disease. glutamic acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarization around one second apart, and this firing pattern is similar to what is known as paroxysmal depolarizing shift in epileptic attacks. This change in the resting membrane potential at seizure foci could cause spontaneous opening of voltage activated calcium channels, leading to glutamic acid release and further depolarization.

Among these are photosynthesis, the Krebs cycle, whole-body and cellular pH regulation, and volume regulation. Since bicarbonate is charged it is not permeable to lipid bilayers. Mammalian membranes thus contain bicarbonate transport proteins to facilitate the specific transmembrane movement of HCO3(-). Bicarbonate ion is an anion that consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens. The bicarbonate ion carries a negative one formal charge and is the conjugate base of carbonic acid, H2CO3. The carbonate radical is an elusive and strong one-electron oxidant. Bicarbonate in equilibrium with carbon dioxide constitutes the main physiological buffer. The bicarbonate-carbon dioxide pair stimulates the oxidation, peroxidation and nitration of several biological targets. The demonstration that the carbonate radical existed as an independent species in aqueous solutions at physiological pH and temperature renewed the interest in the pathophysiological roles of this radical and related species. The carbonate radical has been proposed to be a key mediator of the oxidative damage resulting from peroxynitrite production, xanthine oxidase turnover and superoxide dismutase1 peroxidase activity. The carbonate radical has also been proposed to be responsible for the stimulatory effects of the bicarbonate-carbon dioxide pair on oxidations mediated by hydrogen peroxide/transition metal ions. The ultimate precursor of the carbonate radical anion being bicarbonate, carbon dioxide, peroxymonocarbonate or complexes of transition metal ions with bicarbonate-derived species remains a matter of debate. The carbonate radical mediates some of the pathogenic effects of peroxynitrite. The carbonate radical as the oxidant produced from superoxide dismutase (EC 1.15.1.1, SOD1) peroxidase activity. Peroxymonocarbonate is a biological oxidant, whose existence is in equilibrium with hydrogen peroxide and bicarbonate.

In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Organic phosphates are important in biochemistry, biogeochemistry and ecology. Phosphate (Pi) is an essential component of life. In biological systems, phosphorus is found as a free phosphate ion in solution and is called inorganic phosphate, to distinguish it from phosphates bound in various phosphate esters. Inorganic phosphate is generally denoted Pi and at physiological (neutral) pH primarily consists of a mixture of HPO<sup>2-</sup><sub>4</sub> and H<sub>2</sub>PO<sup>-</sup><sub>4</sub> ions. phosphates are most commonly found in the form of adenosine phosphates, (AMP, ADP and ATP) and in DNA and RNA and can be released by the hydrolysis of ATP or ADP. Similar reactions exist for the other nucleoside diphosphates and triphosphates. Phosphoanhydride bonds in ADP and ATP, or other nucleoside diphosphates and triphosphates, contain high amounts of energy which give them their vital role in all living organisms. Phosphate must be actively transported into cells against its electrochemical gradient. In vertebrates, two unrelated families of Na+-dependent Pi transporters carry out this task. Remarkably, the two families transport different Pi species: whereas type II Na+/Pi cotransporters (SCL34) prefer divalent HPO4(2), type III Na+/Pi cotransporters (SLC20) transport monovalent H2PO4. The SCL34 family comprises both electrogenic and electroneutral members that are expressed in various epithelia and other polarized cells. Through regulated activity in apical membranes of the gut and kidney, they maintain body Pi homeostasis, and in salivary and mammary glands, liver, and testes they play a role in modulating the Pi content of luminal fluids. Phosphate levels in the blood play an important role in hormone signaling and in bone homeostasis. In classical endocrine regulation, low serum phosphate induces the renal production of the seco-steroid hormone 1,25-dihydroxyvitamin D3 (1,25(OH)2D3).This active metabolite of vitamin D acts to restore circulating mineral (i.e. phosphate and calcium) levels by increasing absorption in the intestine, reabsorption in the kidney, and mobilization of calcium and phosphate from bone. Thus, chronic renal failure is associated with hyperparathyroidism, which in turn contributes to osteomalacia (softening of the bones). Another complication of chronic renal failure is hyperphosphatemia (low levels of phosphate in the blood). Hyperphosphatemia (excess levels of phosphate in the blood) is a prevalent condition in kidney dialysis patients and is associated with increased risk of mortality. Hypophosphatemia (hungry bone syndrome) has been associated to postoperative electrolyte aberrations and after parathyroidectomy. (PMID: 17581921, 11169009, 11039261, 9159312, 17625581)Fibroblast growth factor 23 (FGF-23) has recently been recognized as a key mediator of phosphate homeostasis, its most notable effect being promotion of phosphate excretion. FGF-23 was discovered to be involved in diseases such as autosomal dominant hypophosphatemic rickets, X-linked hypophosphatemia, and tumor-induced osteomalacia in which phosphate wasting was coupled to inappropriately low levels of 1,25(OH)2D3. FGF-23 is regulated by dietary phosphate in humans. In particular it was found that phosphate restriction decreased FGF-23, and phosphate loading increased FGF-23.14265-44-2C00009106118367CPD-85871032OP(O)(O)=OH3O4PInChI=1S/H3O4P/c1-5(2,3)4/h(H3,1,2,3,4)NBIIXXVUZAFLBC-UHFFFAOYSA-Nphosphoric acid97.995297.9768950963phosphoric acid0-2DBMET00532FDB022617Nfb orthophosphate;O-phosphoric acid;Ortho-phosphate;Orthophosphate (po43-);Orthophosphate(3-);Phosphate;Phosphate (po43-);Phosphate anion(3-);Phosphate ion (po43-);Phosphate ion(3-);Phosphate trianion;Phosphate(3-);Phosphoric acid ion(3-);Pi;[po4](3-);Orthophosphate;Phosphate ion;Po4(3-);Phosphoric acid;Orthophosphoric acid;Phosphoric acid ionPW_C001104Pi2448488145818188312980317631417674925001027294727374631292931667236366138512342492244753150312751587520797521610053171115351112538110354471205543129557313356051355625108569365848143585514659111475941151604015561001616294107648717866911016714117684218868891607161205718920672122117306198738921074022127436163747522281962258258227101182411013425711748132117611151177321311904170119271641201428112728290132632233481917422553044235031542435318436923227701825377194293772171347794033677966130780483327805732978245353786693318002236889279308938313839479638411055839011064039111323594115845398116206109119982406120069122120699407121057124121216125121268429121352121121409123121423382121852405123304119123621118123786136123838464123968447123981399124405376124948472125362479125446297125774481125954299126221478126594300126604298126723484126904501127413388127783209128166395128177513128315389148Oxalacetic acidHMDB0000223Oxaloacetic acid, also known as oxosuccinic acid or oxalacetic acid, is a four-carbon dicarboxylic acid appearing as an intermediate of the citric acid cycle.

Biotin is also known as vitamin H or B7 or coenzyme R. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk. Biotin has been recognized as an essential nutrient. Our biotin requirement is fulfilled in part through diet, through endogenous reutilization of biotin and perhaps through capture of biotin generated in the intestinal flora. The utilization of biotin for covalent attachment to carboxylases and its reutilization through the release of carboxylase biotin after proteolytic degradation constitutes the 'biotin cycle'. Biotin deficiency is associated with neurological manifestations, skin rash, hair loss and metabolic disturbances that are thought to relate to the various carboxylase deficiencies (metabolic ketoacidosis with lactic acidosis). It has also been suggested that biotin deficiency is associated with protein malnutrition, and that marginal biotin deficiency in pregnant women may be teratogenic. Biotin acts as a carboxyl carrier in carboxylation reactions. There are four biotin-dependent carboxylases in mammals: those of propionyl-CoA (PCC), 3-methylcrotonyl-CoA (MCC), pyruvate (PC) and acetyl-CoA carboxylases (isoforms ACC-1 and ACC-2). All but ACC-2 are mitochondrial enzymes. The biotin moiety is covalently bound to the epsilon amino group of a Lysine residue in each of these carboxylases in a domain 60-80 amino acids long. The domain is structurally similar among carboxylases from bacteria to mammals. There are four biotin-dependent carboxylases in mammals: those of propionyl-CoA (PCC), 3-methylcrotonyl-CoA (MCC), pyruvate (PC) and acetyl-CoA carboxylases (isoforms ACC-1 and ACC-2).

The domain is structurally similar among carboxylases from bacteria to mammals. Evidence is emerging that biotin participates in processes other than classical carboxylation reactions. Specifically, novel roles for biotin in cell signaling, gene expression, and chromatin structure have been identified in recent years. Human cells accumulate biotin by using both the sodium-dependent multivitamin transporter and monocarboxylate transporter 1. These transporters and other biotin-binding proteins partition biotin to compartments involved in biotin signaling: cytoplasm, mitochondria, and nuclei. The activity of cell signals such as biotinyl-AMP, Sp1 and Sp3, nuclear factor (NF)-kappaB, and receptor tyrosine kinases depends on biotin supply. Consistent with a role for biotin and its catabolites in modulating these cell signals, greater than 2000 biotin-dependent genes have been identified in various human tissues. Many biotin-dependent gene products play roles in signal transduction and localize to the cell nucleus, consistent with a role for biotin in cell signaling. Posttranscriptional events related to ribosomal activity and protein folding may further contribute to effects of biotin on gene expression. Finally, research has shown that biotinidase and holocarboxylase synthetase mediate covalent binding of biotin to histones (DNA-binding proteins), affecting chromatin structure; at least seven biotinylation sites have been identified in human histones. Biotinylation of histones appears to play a role in cell proliferation, gene silencing, and the cellular response to DNA repair. Roles for biotin in cell signaling and chromatin structure are consistent with the notion that biotin has a unique significance in cell biology.

Glyoxylic acid is a liquid with a melting point of -93°C and a boiling point of 111°C. It is an intermediate of the glyoxylate cycle, which enables certain organisms to convert fatty acids into carbohydrates. The conjugate base of glyoxylic acid is known as glyoxylate (PMID: 16396466). In humans, glyoxylate is produced via two pathways: (1) through the oxidation of glycolate in peroxisomes and (2) through the catabolism of hydroxyproline in mitochondria. In the peroxisomes, glyoxylate is converted into glycine by glyoxylate aminotransferase (AGT1) or into oxalate by glycolate oxidase. In the mitochondria, glyoxylate is converted into glycine by mitochondrial glyoxylate aminotransferase AGT2 or into glycolate by glycolate reductase. A small amount of glyoxylate is converted into oxalate by cytoplasmic lactate dehydrogenase. Glyoxylic acid is found to be associated with primary hyperoxaluria I, which is an inborn error of metabolism. Under certain circumstances, glyoxylate can be a nephrotoxin and a metabotoxin. A nephrotoxin is a compound that causes damage to the kidney and kidney tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. High levels of glyoxylate are involved in the development of hyperoxaluria, a key cause of nephrolithiasis (commonly known as kidney stones). Glyoxylate is both a substrate and inductor of sulfate anion transporter-1 (SAT-1), a gene responsible for oxalate transportation, allowing it to increase SAT-1 mRNA expression, and as a result oxalate efflux from the cell. The increased oxalate release allows the buildup of calcium oxalate in the urine, and thus the eventual formation of kidney stones. As an aldehyde, glyoxylate is also highly reactive and will modify proteins to form advanced glycation products (AGEs).298-12-4C0004876016891GLYOX740DB04343OC(=O)C=OC2H2O3InChI=1S/C2H2O3/c3-1-2(4)5/h1H,(H,4,5)HHLFWLYXYJOTON-UHFFFAOYSA-N2-oxoacetic acid74.035574.000393930.481glyoxylic acid0-1FDB001478Formylformate;Formylformic acid;Glyoxalate;Glyoxalic acid;Glyoxylate;Glyoxylic acid;Oxalaldehydate;Oxalaldehydic acid;Oxoacetate;Oxoacetic acid;Oxoethanoate;Oxoethanoic acid;A-ketoacetate;A-ketoacetic acid;Alpha-ketoacetate;Alpha-ketoacetic acid;Glyoxalsaeure;Glyoxylsaeure;α-ketoacetate;α-ketoacetic acid;OxaldehydatePW_C000075Glyoxal30434413541910354531205579133572910860041476456107124752491523222242614315426323187809411212002740612214140712469311912540547912629848112694550112786220678GlycineHMDB0000123Glycine is a simple, nonessential amino acid, although experimental animals show reduced growth on low-glycine diets. The average adult ingests 3 to 5 grams of glycine daily. Glycine is involved in the body's production of DNA, phospholipids and collagen, and in release of energy. Glycine levels are effectively measured in plasma in both normal patients and those with inborn errors of glycine metabolism. (http://www.dcnutrition.com/AminoAcids/) Nonketotic hyperglycinaemia (OMIM 606899) is an autosomal recessive condition caused by deficient enzyme activity of the glycine cleavage enzyme system (EC 2.1.1.10). The glycine cleavage enzyme system comprises four proteins: P-, T-, H- and L-proteins (EC 1.4.4.2, EC 2.1.2.10 and EC 1.8.1.4 for P-, T- and L-proteins). Mutations have been described in the GLDC (OMIM 238300), AMT (OMIM 238310), and GCSH (OMIM 238330) genes encoding the P-, T-, and H-proteins respectively. The glycine cleavage system catalyses the oxidative conversion of glycine into carbon dioxide and ammonia, with the remaining one-carbon unit transferred to folate as methylenetetrahydrofolate. It is the main catabolic pathway for glycine and it also contributes to one-carbon metabolism. Patients with a deficiency of this enzyme system have increased glycine in plasma, urine and cerebrospinal fluid (CSF) with an increased CSF: plasma glycine ratio.

metabolic disorders but also of other origin (infections, etc.). Respiratory chain defects account for most of the metabolic causes of lactic acid accumulation. Often alanine is also high. A urine spectrum indicating an increased lactic acid and alanine concentration is shown.DiseasePW_X000106Context10647019ProteinMutated471105CompoundIncreased1010[OMIM: Entry 312170](http://www.ncbi.nlm.nih.gov/entrez/dispomim.cgi?id=312170)106Context1011[Uniprot: P08559](http://www.uniprot.org/uniprot/P08559)106Context1012Engelke, U., van der Graaf, M., Heerschap, A., Hoenderop, S., Moolenaar, S., Morava, E., Wevers, R.
