what type of chemicals are dhea and androstenedione
Dehydroepiandrosterone Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone.[2][5] It is one of the most abundant circulating steroids in humans,[6] in whom it is produced in the adrenal glands,[7] the gonads, and the brain,[8] where it functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids.[5][9] However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors,[10] and acting as a neurosteroid and neurotrophin.[11]
