Metabolite Identification
Common Name3-Methoxytyramine
Description3-3-3-methoxytyramine, also known as 3-O-methyldopamine, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 3-3-3-methoxytyramine is possibly soluble (in water) and a very strong basic compound (based on its pKa). 3-3-3-methoxytyramine exists in all living organisms, ranging from bacteria to humans. 3-3-3-methoxytyramine participates in a number of enzymatic reactions, within cattle. In particular, 3-3-3-methoxytyramine can be converted into homovanillin through its interaction with the enzyme amine oxidase [flavin-containing] a. In addition, 3-3-3-methoxytyramine and pyrocatechol can be biosynthesized from dopamine and guaiacol through the action of the enzyme catechol O-methyltransferase. In cattle, 3-3-methoxytyramine is involved in the metabolic pathway called the tyrosine metabolism pathway. 3-3-3-methoxytyramine is a potentially toxic compound.
