Metabolite Identification
Common NameMetanephrine
DescriptionMetanephrine, also known as metanephrine, 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. Metanephrine is possibly soluble (in water) and a very strong basic compound (based on its pKa). Metanephrine participates in a number of enzymatic reactions, within cattle. In particular, Metanephrine can be converted into 3-methoxy-4-hydroxyphenylglycolaldehyde; which is mediated by the enzyme amine oxidase [flavin-containing] a. In addition, Metanephrine and pyrocatechol can be biosynthesized from epinephrine and guaiacol; which is mediated by the enzyme catechol O-methyltransferase. In cattle, metanephrine is involved in the metabolic pathway called the tyrosine metabolism pathway.
