<unk> , also known as androst-5-en-3β-ol-17-one, is a naturally occurring androstane steroid and a 17-ketosteroid. It is closely related structurally to androstenediol (androst-5-ene-3β,17β-diol), androstenedione (androst-4-ene-3,17-dione), and testosterone (androst-4-en-17β-ol-3-one).<unk>  is the 5-dehydro analogue of epiandrosterone (5α-androstan-3β-ol-17-one) and is also known as 5-dehydroepiandrosterone or as δ5-epiandrosterone. Isomers The term<unk> " is ambiguous chemically because it does not include the specific positions within epiandrosterone at which hydrogen atoms are missing.<unk>  itself is 5,6-didehydroepiandrosterone or 5-dehydroepiandrosterone. A number of naturally occurring isomers also exist and may have similar activities. Some isomers of<unk>  are 1-dehydroepiandrosterone (1-androsterone) and 4-dehydroepiandrosterone. These isomers are also technically "DHEA", since they are<unk> s in which hydrogens are removed from the epiandrosterone skeleton. Dehydroandrosterone <unk>  is the 3α-epimer of<unk>  and is also an endogenous androgen.
