Metabolite Identification
Common NameEtiocholanolone
DescriptionEtiocholanolone, also known as Etiocholanolone, 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, etiocholanolone is considered to be a steroid lipid molecule. Etiocholanolone exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Etiocholanolone exists in all living organisms, ranging from bacteria to humans. Etiocholanolone can be biosynthesized from etiocholanedione through the action of the enzyme aldo-keto reductase family 1 member C4. In cattle, etiocholanolone is involved in the metabolic pathway called the androstenedione metabolism pathway.
