Dehydroepiandrosterone sulfate, abbreviated as DHEA sulfate or DHEA-S, also known as androstenolone sulfate, is an endogenous androstane steroid that is produced by the adrenal cortex. [1] It is the 3β- sulfate ester and a metabolite of dehydroepiandrosterone (DHEA) and circulates in far greater relative concentrations than DHEA. [ 2 ]
Levels of DHEA-S in circulation are approximately 250 to 300 times those of DHEA. [20] DHEA-S in turn can be converted back into DHEA in peripheral tissues via steroid sulfatase (STS). [54] [55] The terminal half-life of DHEA is short at only 15 to 30 minutes. [56] In contrast, the terminal half-life of DHEA-S is far longer, at 7 to 10 hours. [56]
16α-Hydroxydehydroepiandrosterone sulfate (16α-OH-DHEA-S), also known as 16α-hydroxy-17-oxoandrost-5-en-3β-yl sulfate, is an endogenous, naturally occurring steroid and a metabolic intermediate in the production of estriol from dehydroepiandrosterone (DHEA) during pregnancy. [1] [2] It is the C3β sulfate ester of 16α-hydroxy-DHEA. [3] [4]
Depression. DHEA levels are lower in those with depression, so supplementation may help.. A 2005 placebo-controlled study looked at men and women aged 45 to 65 with midlife-onset major or minor ...
Dehydroepiandrosterone sulfate, a major endogenous steroid sulfate. Note the steroid ester at the C3β position. Steroid sulfates are endogenous sulfate esters of steroids. [1] They are formed by steroid sulfotransferases via sulfation of endogenous steroids like cholesterol and steroid hormones. [1]
Prasterone sulfate (brand names Astenile, Mylis, Teloin, others), also known as dehydroepiandrosterone sulfate (DHEA-S), is a naturally occurring androstane steroid which is marketed and used in Japan and other countries as a labor inducer in the treatment of insufficient cervical ripening and dilation during childbirth.
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]
