Metabolite Identification
Common Name16-a-Hydroxypregnenolone
Description16-alpha-hydroxypregnenolone, also known as (3beta,16alpha)-3,16-dihydroxypregn-5-en-20-one, is classified as a gluco/mineralocorticoid, a progestogin or aprogestogin derivative. Gluco/mineralocorticoids are steroids with a structure based on a hydroxylated prostane moiety. Thus, 16-alpha-hydroxypregnenolone is a steroid lipid molecule. 16-alpha-hydroxypregnenolone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 16-alpha-hydroxypregnenolone can be found primarily in blood, urine and in human umbilical cord tissue. Within the cell, 16-alpha-hydroxypregnenolone is primarily located in the membrane, and in the nucleus bound to cytoplasmic glucocorticoid receptors. 16-alpha-hydroxypregnenolone exists in all vertebrates. 16-a-Hydroxypregnenolone is a normal urinary metabolite with increased total excretion in newborn infants with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (PMID 6980322 ).
