Metabolite Identification
Common Name5alpha-Cholesta-7,24-dien-3beta-ol
Description5alpha-Cholesta-7,24-dien-3beta-ol belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 5alpha-cholesta-7,24-dien-3beta-ol is considered to be a sterol lipid molecule. 5alpha-Cholesta-7,24-dien-3beta-ol is involved in the biosynthesis of steroids. 5alpha-Cholesta-7,24-dien-3beta-ol is reversibly converted into 5alpha-cholest-7-en-3beta-ol by delta24-sterol reductase (EC 1.3.1.72). 5alpha-Cholesta-7,24-dien-3beta-ol is also converted into zymosterol by cholestenol delta-isomerase (EC 5.3.3.5). 5alpha-Cholesta-7,24-dien-3beta-ol is also converted into 7-Dehydrodesmosterol. 5alpha-Cholesta-7,24-dien-3beta-ol is a substrate for 3-beta-hydroxysteroid-delta(8),delta(7)-isomerase.
