16α-Hydroxy-DHEA

16α-Hydroxydehydroepiandrosterone (16α-hydroxy-DHEA or 16α-OH-DHEA) is an endogenous metabolite of dehydroepiandrosterone (DHEA). Both 16α-OH-DHEA and its 3β-sulfate ester, 16α-OH-DHEA-S, are intermediates in the biosynthesis of estriol from dehydroepiandrosterone (DHEA).[1] 16α-OH-DHEA has estrogenic activity.[2]
