Terpenoid Backbone Biosynthesis 1540198538Saccharomyces cerevisiae
The biosynthesis of steroids begins with acetyl coa being turned into acetoacetyl through a acetoacetyl CoA thiolase. Acetoacetyl -CoA reacts with an acetyl-CoA and water through a 3-hydroxy 3-methylglutaryl coenzyme A synthase resulting in the release of coenzyme A, hydrogen ion and (S)-3-hydroxy-3-methylglutaryl-CoA. The latter compound reacts with NADPH and a hydrogen ion through a 3-hydroxy-3-methylglutaryl-coenzyme A resulting in the release of coenzyme A , NADP and mevalonate. Mevalonate is then phosphorylated through an ATP driven kinase mevalonate kinase resulting in the release of ADP, hydrogen ion and mevalonate 5-phosphate. The latter compound is phosphorylated through an ATP driven kinase, phosphomevalonate kinase resulting in the release of ADP and mevalonate diphosphate. This latter compound then reacts with an ATP driven mevalonate diphosphate decarboxylase resulting in the release of ADP, carbon dioxide, a phosphate and a isopentenyl diphosphate. The latter compound can be isomerized into dimethylallyl diphosphate or reacth with a dimethylallyl diphosphate to produce geranyl diphosphate. Geranyl diphosphate reacts with a isopentenyl through a farnesyl diphosphate synthase resulting in the release of diphosphate and farnesyl diphosphate.
Farnesyl diphosphate has three different fates:
1.-Producing hexaprenyl diphosphate in the mitocondrial inner membrane by reacting with 3 isopentenyl diphosphate
2.-Producing geranylgeranyl diphosphate in the cytoplasm by reacting with one isopentenyl diphosphate
3.-Producing a dolichol precursor in the ER by reacting with 13 isopentenyl diphosphates.

terpenoid Biosynthesis 1539750211Bacteria
Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway, and the non-mevalonate pathway or the MEP/DOXP pathway, for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants, the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil monoterpenes and linalyl acetate, some sesquiterpenes, diterpenes, and carotenoids and phytol. The mevalonate pathway, operating in the cytosol, gives rise to triterpenes, sterols, and most
sesquiterpenes.

Terpin hydrate Drug MetabolismHomo sapiens
Terpin hydrate is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Terpin hydrate passes through the liver and is then excreted from the body mainly through the kidney.
