Metabolite Identification
Common Name16a-Hydroxyandrost-4-ene-3,17-dione
Description16a-Hydroxyandrost-4-ene-3,17-dione, also known as 4-androsten-16alpha-ol-3,17-dione or 16alpha-ohad, belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. Thus, 16a-hydroxyandrost-4-ene-3,17-dione is considered to be a steroid lipid molecule. 16a-Hydroxyandrost-4-ene-3,17-dione is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.

Enzymes

General function:
Involved in 3-beta-hydroxy-delta5-steroid dehydrogenase activity
Specific function:
3-beta-HSD is a bifunctional enzyme, that catalyzes the oxidative conversion of Delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. Efficiently catalyzes the transformation of pregnenolone to progesterone, 17-alpha-hydroxypregnenolone to 17-alpha-hydroxyprogesterone, DHEA to 4-androstenedione, dihydrotestosterone to 5-alpha-androstane-3 beta,17 beta-diol, dehydroepiandrosterone to androstenedione and 5-alpha-androstan-3 beta,17 beta-diol to 5-alpha-dihydrotestosterone.
