Pyridoxal phosphate is an organic compound with the formula C8H10NO6P, formed by combining vitamin B6 with phosphoric acid, including pyridoxal, pyridoxamine, pyridoxine, and in the form of phosphate esters in the body. Among them, pyridoxal phosphate and pyridoxamine phosphate can be converted to each other Chemicalbook, both of which are active types. Pyridoxal phosphate is the active form of vitamin B6. Several reactions catalyzed by pyridoxal phosphate are: transamination, α-decarboxylation, β-decarboxylation, β-elimination, γ-elimination, racemic and aldol
