Pyridoxal 5'-​phosphate monohydrate

Pyridoxal 5'-phosphate hydrate, the active form of vitamin B6, is an essential cofactor for multiple enzymes, including aromatic l-amino acid decarboxylase that catalyzes the final stage in the production of the neurotransmitters dopamine and serotonin. Pyridoxal 5'-phosphate hydrate is the most important coenzyme variant in the process of vitamin B6 intracellular phosphorylation and is interconvertible with other variants, including pyridoxine 5′‐phosphate (PNP) and pyridoxamine 5′‐phosphate (PMP)[1][2].
