Natural Pure Vitamin B6 Pyridoxal 5-phosphate 98% Wholesale Bulk

Pyridoxal phosphate (PLP, the main metabolically active form of vitamin B6) is a multifunctional coenzyme involved in the metabolism of amino compounds. Enzymes that use it as a coenzyme factor are called PLP-dependentenzymes (PLP-DEs), and they play an important role in the metabolism of sugars, lipids and amino acids. The main ones are the biosynthesis of amino acids and biomolecules such as the neurotransmitters serotonin, dopamine,  norepinephrine, gamma-aminobutyric acid (GABA) and histamine.

PLP is so important that it is involved in the activities of more than 140 PLP-dependent enzymes, accounting for about 4% of all taxonomic activities.The versatility of PLP comes from its electrophilic nature:PLP is covalently bound to the substrate by forming an external aldimine at the beginning of the reaction, and then different types of carbon-negative reaction intermediates can be stabilized by PLP through resonance effects.This function of PLP is also known as "electron trap". In addition to the electron-withdrawal effect, the acidic and basic groups that assist in proton transfer are equally important since almost all PLP-dependent reactions produce cationic and anionic intermediates.

1)As an active ingredient of Vitamin B6 in the body, which can be used for biological fermentation to production coenzyme.
2)It can also be used to synthesize neurotransmitters, histamine and gamma-aminobutyric acid;
3)It can also be used as food/health product additives.
