Metabolite Identification
Common Name4-alpha-Methyl-5-alpha-cholest-7-en-3-beta-ol
Description4-alpha-Methyl-5-alpha-cholest-7-en-3-beta-ol is involved in the steroid biosynthesis pathway. In this pathway, 4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol is enzymatically converted to 4-alpha-methyl-5-alpha-cholest-7-en-3-one via the enzyme 3-keto-steroid reductase (EC: 1.1.1.270) and the cofactor NADP(+). This enzyme is responsible for the reduction of the keto group on the C-3 of sterols. (Pathway Commons). Steroid biosynthesis is an anabolic metabolic pathway that produces steroids from simple precursors. This pathway is carried out in different ways in animals than in many other organisms, making the pathway a common target for antibiotics and other anti-infective drugs. In addition, steroid metabolism in humans is the target of cholesterol-lowering drugs such as statins. (Wikipedia).
