Metabolite Identification
Common NamePyridoxamine
DescriptionPyridoxamine, also known as PM, belongs to the class of organic compounds known as pyridoxamine 5'-phosphates. These are heterocyclic aromatic compounds containing a pyridoxamine that carries a phosphate group at the 5'-position. Pyridoxamine is possibly soluble (in water) and a very strong basic compound (based on its pKa). Pyridoxamine exists in all living species, ranging from bacteria to humans. Pyridoxamine participates in a number of enzymatic reactions, within cattle. In particular, Pyridoxamine can be converted into pyridoxal; which is catalyzed by the enzyme pyridoxine-5'-phosphate oxidase. In addition, Pyridoxamine can be converted into pyridoxamine 5'-phosphate through its interaction with the enzyme pyridoxal kinase. In cattle, pyridoxamine is involved in the metabolic pathway called the vitamin B6 metabolism pathway.
