Metabolite Identification
Common NamePyridoxamine 5'-phosphate
DescriptionPyridoxamine 5'-phosphate, also known as pyridoxamine phosphoric acid or pyridoxamine-p, 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 5'-phosphate is possibly soluble (in water) and a very strong basic compound (based on its pKa). Pyridoxamine 5'-phosphate exists in all living species, ranging from bacteria to humans. Pyridoxamine 5'-phosphate participates in a number of enzymatic reactions, within cattle. In particular, Pyridoxamine 5'-phosphate can be biosynthesized from pyridoxamine; which is catalyzed by the enzyme pyridoxal kinase. In addition, Pyridoxamine 5'-phosphate can be converted into pyridoxal 5'-phosphate through the action of the enzyme pyridoxine-5'-phosphate oxidase. In cattle, pyridoxamine 5'-phosphate is involved in the metabolic pathway called the vitamin B6 metabolism pathway.
