Metabolite Identification
Common NameEstriol
DescriptionEstriol, also known as 16a,17b-estriol or ovestin, belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, estriol is considered to be a steroid lipid molecule. Estriol is a drug which is used as a test to determine the general health of an unborn fetus. Estriol exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Estriol participates in a number of enzymatic reactions, within cattle. In particular, Estriol can be biosynthesized from 16a-hydroxyestrone; which is mediated by the enzyme estradiol 17-beta-dehydrogenase 1. In addition, Estriol can be biosynthesized from estradiol; which is mediated by the enzyme cytochrome P450 3A5. In cattle, estriol is involved in the metabolic pathway called the estrone metabolism pathway. Estriol is a potentially toxic compound.
