Metabolite Identification
Common Name21-Hydroxypregnenolone
Description21-Hydroxypregnenolone, also known as 21-hydroxypregnenolone, 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. Thus, 21-hydroxypregnenolone is considered to be a steroid lipid molecule. 21-Hydroxypregnenolone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 21-Hydroxypregnenolone participates in a number of enzymatic reactions, within cattle. In particular, 21-Hydroxypregnenolone can be converted into deoxycorticosterone through the action of the enzyme 3-beta-HSD 1. In addition, 21-Hydroxypregnenolone can be biosynthesized from pregnenolone through its interaction with the enzyme steroid 21-hydroxylase. In cattle, 21-hydroxypregnenolone is involved in the metabolic pathway called the steroidogenesis pathway.
