Common Name5-b-Cholestane-3a ,7a ,12a-triol
Description5-b-Cholestane-3a ,7a ,12a-triol is an intermediate in Bile acid biosynthesis. 5-b-Cholestane-3a ,7a ,12a-triol is the second to last step of synthesis of 5beta-Cyprinolsulfate. It is converted from 7alpha,12alpha-Dihydroxy-5beta-cholestan-3-one via enzymatic reaction then it is coneverted to 3alpha,7alpha,12alpha,26-Tetrahydroxy-5beta-cholestane via the enzyme cytochrome P450(EC.1.14.13.15). This compound inhibits la-Hydroxylation, (PMID: 7937829 ). It is the byproduct of Cholestanetetraol 26-dehydrogenase (EC 1.1.1.161), and the reaction that cataylzes it is classified as a small molecule reaction. (BioCyc).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha-androstan-3-alpha,17-beta-diol (3-alpha-diol). Also has some 20-alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route.
