4321 3-Hydroxy-3-methylglutaryl-CoA 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) is formed when Acetyl-CoA condenses with acetoacetyl-CoA in a reaction that is catalyzed by the enzyme HMG-CoA synthase in the mevalonate pathway or mevalonate-dependent (MAD) route, an important cellular metabolic pathway present in virtually all organisms. HMG-CoA reductase (EC 1.1.1.34) inhibitors, more commonly known as statins, are cholesterol-lowering drugs that have been widely used for many years to reduce the incidence of adverse cardiovascular events. HMG-CoA reductase catalyzes the rate-limiting step in the mevalonate pathway and these agents lower cholesterol by inhibiting its synthesis in the liver and in peripheral tissues. Androgen also stimulates lipogenesis in human prostate cancer cells directly by increasing transcription of the fatty acid synthase and HMG-CoA-reductase genes.

Demethylation and glucuronidation may also occur. Oxidation of organophosphorus pesticides may result in moderately toxic products. In general, phosphorothioates are not directly toxic but require oxidative metabolism to the proximal toxin. The glutathione transferase reactions produce products that are, in most cases, of low toxicity. Paraoxonase (PON1) is a key enzyme in the metabolism of organophosphates. PON1 can inactivate some organophosphates through hydrolysis. PON1 hydrolyzes the active metabolites in several organophosphates insecticides as well as, nerve agents such as soman, sarin, and VX. The presence of PON1 polymorphisms causes there to be different enzyme levels and catalytic efficiency of this esterase, which in turn suggests that different individuals may be more susceptible to the toxic effect of organophosphate exposure. Not listed by IARC. This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation. 2014-08-29T06:10:46Z 2026-04-05T14:25:29Z 3-hydroxy-3-methylglutaryl-CoA C00356 15467 3-HYDROXY-3-METHYL-GLUTARYL-COA HMG true C[C@](O)(CC(O)=O)CC(=O)SCCNC(=O)CCNC(=O)C(O)C(C)(C)COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H]([C@H](O)[C@@H]1OP(O)(O)=O)N1C=NC2=C1N=CN=C2N C27H44N7O20P3S InChI=1S/C27H44N7O20P3S/c1-26(2,21(40)24(41)30-5-4-15(35)29-6-7-58-17(38)9-27(3,42)8-16(36)37)11-51-57(48,49)54-56(46,47)50-10-14-20(53-55(43,44)45)19(39)25(52-14)34-13-33-18-22(28)31-12-32-23(18)34/h12-14,19-21,25,39-40,42H,4-11H2,1-3H3,(H,29,35)(H,30,41)(H,36,37)(H,46,47)(H,48,49)(H2,28,31,32)(H2,43,44,45)/t14-,19-,20-,21?,25-,27+/m1/s1 CABVTRNMFUVUDM-MIGRVSMKSA-N 911.659 911.157467109 Endogenous Solid HMDB01375 388357 Williamson I P; Rodwell V W Isolation and purification of 3-hydroxy-3-methylglutaryl-coenzyme A by ion-exchange chromatography.
