Pyridoxal 5′-Phosphate

Meaning

Pyridoxal 5′-Phosphate (P5P) is the biologically active coenzyme form of Vitamin B6, an essential water-soluble vitamin that plays a ubiquitous and critical role in human metabolism. P5P functions as a necessary cofactor for over 140 enzyme reactions, predominantly involved in amino acid metabolism, neurotransmitter synthesis, and the crucial processes of gluconeogenesis and glycogenolysis. Its bioavailability is superior to its precursor forms, making it a vital clinical nutrient for supporting numerous hormonal and neurological pathways.
