PW122138 View Pathway	signaling Vitamin C in the Brain Homo sapiens Ascorbate (Vitamin C) is a very important molecule in the brain. Ascorbate is transported into brain through Sodium-dependent Vitamin C Transporter-2 (SVCT2), and will be reduced to dehydroascorbic acid, which is the oxidized form of ascorbate. Dehydroascorbic acid is transported into extracellular place and enter astrocyte space via Solute carrier family 2, facilitated glucose transporter members (GLUT family). Once dehydroascorbic acid in astrocyte cells, it is rapidly reduced to ascorbate to do further reactions that are associated with other pathways. Ascorbate is proposed as a neuromodulator of glutamatergic, dopaminergic, cholinergic and GABAergic transmission and related behaviors; it also has a number of other important functions, participating as a co-factor in several enzyme reactions including catecholamine synthesis, collagen production and regulation of HIF-1α.

PW088340 View Pathway	metabolic Vitamin K Metabolism Rattus norvegicus Vitamin K describes a group of lipophilic, hydrophobic vitamins that exist naturally in two forms (and synthetically in three others): vitamin K1, which is found in plants, and vitamin K2, which is synthesized by bacteria. Vitamin K is an important dietary component because it is necessary as a cofacter in the activation of vitamin K dependent proteins. Metabolism of vitamin K occurs mainly in the liver. In the first step, vitamin K is reduced to its quinone form by a quinone reductase such as NAD(P)H dehydrogenase. Reduced vitamin K is the form required to convert vitamin K dependent protein precursors to their active states. It acts as a cofactor to the integral membrane enzyme vitamin K-dependent gamma-carboxylase (along with water and carbon dioxide as co-substrates), which carboxylates glutamyl residues to gamma-carboxy-glutamic acid residues on certain proteins, activating them. Each converted glutamyl residue produces a molecule of vitamin K epoxide, and certain proteins may have more than one residue requiring carboxylation. To complete the cycle, the vitamin K epoxide is returned to vitamin K via the vitamin K epoxide reductase enzyme, also an integral membrane protein. The vitamin K dependent proteins include a number of important coagulation factors, such as prothrombin. Thus, warfarin and other coumarin drugs act as anticoagulants by blocking vitamin K epoxide reductase.
