特徴

• Dehydroepiandrosterone (DHEA) is a C19 steroid also known as 5-androsten-3 beta-ol-17-one. DHEA and DHEAS (an active, sulfated form of DHEA), are endogenous hormones secreted by the adrenal cortex in primates and a few non-primate species in response to ACTH. DHEA is a steroid precursor of both androgens and estrogens, and thus is often called 'the mother hormone'. Endogenous DHEA is thought to be important in several endocrine processes, but current medical use of DHEA is limited to controlled clinical trials.
