Chemical Information
FooDB Name17-α-hydroxypregnenolone
Description17-α-hydroxypregnenolone, also known as (3beta)-3,17-dihydroxypregn-5-en-20-one or 5-pregnen-3b,17a-diol-20-one, belongs to gluco/mineralocorticoids, progestogins and derivatives class of compounds. Those are steroids with a structure based on a hydroxylated prostane moiety. Thus, 17-α-hydroxypregnenolone is considered to be a steroid lipid molecule. 17-α-hydroxypregnenolone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 17-α-hydroxypregnenolone can be found in a number of food items such as strawberry guava, java plum, conch, and chives, which makes 17-α-hydroxypregnenolone a potential biomarker for the consumption of these food products. 17-α-hydroxypregnenolone can be found primarily in blood, as well as in human adrenal cortex and testes tissues. In humans, 17-α-hydroxypregnenolone is involved in a couple of metabolic pathways, which include androgen and estrogen metabolism and steroidogenesis. 17-α-hydroxypregnenolone is also involved in several metabolic disorders, some of which include aromatase deficiency, adrenal hyperplasia type 3 or congenital adrenal hyperplasia due to 21-hydroxylase deficiency, adrenal hyperplasia type 5 or congenital adrenal hyperplasia due to 17 alpha-hydroxylase deficiency, and apparent mineralocorticoid excess syndrome.
