Common Name 7 alpha,26-Dihydroxy-4-cholesten-3-one
Description 7 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).
Synonyms
  1. 4-cholesten-7alpha,26-diol-3-one
