Common Name(3S)-hydroxy-3-methylglutaryl-CoA
Description(3S)-hydroxy-3-methylglutaryl-CoA is a key intermediate in the mevalonate pathway and belongs to the class of coenzyme A derivatives. Its chemical structure features a hydroxyl group at the 3-position of the 3-methylglutaryl moiety, which is essential for its function in metabolic processes. In human biochemistry, (3S)-hydroxy-3-methylglutaryl-CoA is primarily involved in the synthesis of cholesterol and other isoprenoids. The enzyme human 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR; EC 1.1.1.34) catalyzes the conversion of (3S)-hydroxy-3-methylglutaryl-CoA to mevalonic acid, representing the rate-limiting step in cholesterol biosynthesis. This pathway is crucial for maintaining cellular cholesterol homeostasis, influencing various biological functions, including membrane integrity and the synthesis of steroid hormones. The regulation of HMGCR and the levels of (3S)-hydroxy-3-methylglutaryl-CoA are therefore critical for lipid metabolism and overall cellular health. (PMID:35470784 )
