Metabolite Identification
Common NameEpietiocholanolone
DescriptionEpietiocholanolone, also known as 5b-epiandrosterone or M1A, belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. Thus, epietiocholanolone is considered to be a steroid lipid molecule. Epietiocholanolone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
