Metabolite Identification
Common Name3a,11b,21-Trihydroxy-20-oxo-5b-pregnan-18-al
Description3a,11b,21-Trihydroxy-20-oxo-5b-pregnan-18-al belongs to the class of organic compounds known as 21-hydroxysteroids. These are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. 3a,11b,21-Trihydroxy-20-oxo-5b-pregnan-18-al is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 3a,11b,21-Trihydroxy-20-oxo-5b-pregnan-18-al can be biosynthesized from 11b,21-dihydroxy-3,20-oxo-5b-pregnan-18-al; which is mediated by the enzyme aldo-keto reductase family 1 member C4. In cattle, 3a,11b,21-trihydroxy-20-oxo-5b-pregnan-18-al is involved in the metabolic pathway called the steroidogenesis pathway.
