Metabolite Identification
Common Name2-Methoxyestrone
Description2-Methoxyestrone belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, 2-methoxyestrone is considered to be a steroid lipid molecule. 2-Methoxyestrone exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. 2-Methoxyestrone exists in all living organisms, ranging from bacteria to humans. 2-Methoxyestrone and S-adenosylhomocysteine can be biosynthesized from S-adenosylmethionine and 2-hydroxyestrone; which is mediated by the enzyme catechol O-methyltransferase. In cattle, 2-methoxyestrone is involved in the metabolic pathway called the estrone metabolism pathway.
