Pyridoxal phosphate (PLP, the main metabolic active form of vitamin B6) is a multifunctional coenzyme involved in the metabolism of amino compounds. The enzyme with it as coenzyme factor is called PLP dependent enzyme they play an important role in the metabolic processes of sugar, fat and amino acids, mainly the biosynthesis of amino acids and biomolecules, such as neurotransmitters serotonin, dopamine, epinephrine, norepinephrine γ- Aminobutyric acid (GABA) and histamine.
PLP is very important. It participates in the activities of more than 140 PLP dependent enzymes, accounting for about 4% of all classification activities. The versatility of PLP comes from its electrophilicity: PLP covalently binds to the substrate by forming external aldehyde imines at the beginning of the reaction, and then different types of carbon anion reaction intermediates can be stabilized by PLP through resonance effect. This function of PLP is also called "electron trap". In addition to the electron absorption effect, since almost all PLP dependent reactions produce cationic and anionic intermediates, the acidic and basic groups that assist proton transfer are equally important.
Pyridoxal 5-phosphate is an organic synthesis intermediate and pharmaceutical intermediate. It can be used as biochemical reagent in laboratory organic synthesis process and chemical medicine R & D process.
