Metabolite Identification
Common Name7 alpha,26-Dihydroxy-4-cholesten-3-one
Description7 alpha,26-Dihydroxy-4-cholesten-3-one is involved in primary bile acid biosynthesis. 7 alpha,26-Dihydroxy-4-cholesten-3-one is produced from 7 alpha,27-Dihydroxycholesterol through the action of HSD3B7 (EC:1.1.1.181). 7 alpha,26-Dihydroxy-4-cholesten-3-one can then be converted to 7 alpha-Hydroxy-3-oxo-4-cholestenoate by CYP27A (EC:1.14.13.15).

General function:
Involved in 3-beta-hydroxy-delta5-steroid dehydrogenase activity
Specific function:
The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. HSD VII is active against four 7-alpha-hydroxylated sterols. Does not metabolize several different C(19/21) steroids as substrates. Involved in bile acid synthesis.
