Metabolite Identification
Common NameAlloepipregnanolone
DescriptionAlloepipregnanolone, also known as eltanolone, belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogins and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. Thus, alloepipregnanolone is considered to be a steroid. Based on a literature review very few articles have been published on Alloepipregnanolone.
