Metabolite Identification
Common Name17-Hydroxypregnenolone sulfate
Description17-Hydroxypregnenolone sulfate is a precursor steroid. 17-Hydroxypregnenolone is a C21 steroid that is obtained by hydroxylation of pregnenolone at the C17 alpha position.17-Hydroxypregnenolone is considered a prohormone in the formation of dehydroepiandrosterone (DHEA), itself a prohormone of the sex steroids (Wikipedia).
