19-Nordehydroepiandrosterone

19-Nordehydroepiandrosterone

19-Nordehydroepiandrosterone (pronunciation: 19-Nor-de-hydro-epi-androsterone), also known as 19-Nor-DHEA or estr-4-ene-3,17-dione, is a steroid and hormone precursor that is a key intermediate in the biosynthesis of the estrogen estrone and the androgen testosterone.

Etymology

The term "19-Nordehydroepiandrosterone" is derived from its chemical structure. The "19-Nor" prefix indicates the absence of a carbon atom at the 19th position, a characteristic feature of this class of steroids. "Dehydroepiandrosterone" refers to the parent compound, DHEA, from which 19-Nor-DHEA is derived.

Function

19-Nordehydroepiandrosterone is a prohormone, meaning it is a substance that can be converted in the body to other hormones. Specifically, it is a precursor to nandrolone, a potent anabolic steroid. It is also a metabolite of DHEA, a hormone produced by the adrenal glands.
