Class

Small Molecule

Description

16a-Hydroxyestrone, also known as 16a-hydroxyestrone or 16a-hydroxyestrone, belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, 16a-hydroxyestrone is considered to be a steroid lipid molecule. 16a-Hydroxyestrone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 16a-Hydroxyestrone participates in a number of enzymatic reactions, within cattle. In particular, 16a-Hydroxyestrone can be biosynthesized from estrone; which is catalyzed by the enzyme cytochrome P450 3A5. In addition, 16a-Hydroxyestrone can be converted into estriol through its interaction with the enzyme estradiol 17-beta-dehydrogenase 1. In cattle, 16a-hydroxyestrone is involved in the metabolic pathway called the estrone metabolism pathway.
