Common NamePyridoxal 5'-phosphate
DescriptionPyridoxal phosphate, also known as PLP, pyridoxal 5'-phosphate or P5P, is the active form of vitamin B6. It is a coenzyme in a variety of enzymatic reactions. Pyridoxal 5'-phosphate belongs to the class of organic compounds known as pyridoxals and derivatives. Pyridoxals and derivatives are compounds containing a pyridoxal moiety, which consists of a pyridine ring substituted at positions 2,3,4, and 5 by a methyl group, a hydroxyl group, a carbaldehyde group, and a hydroxymethyl group, respectively. Pyridoxal 5'-phosphate is a drug which is used for nutritional supplementation and for treating dietary shortage or imbalance. Pyridoxal 5'-phosphate exists in all living species, ranging from bacteria to humans. In humans, pyridoxal 5'-phosphate is involved in glycine and serine metabolism. Outside of the human body, pyridoxal 5'-phosphate is found, on average, in the highest concentration within cow milk. Pyridoxal 5'-phosphate has also been detected, but not quantified in several different foods, such as soursops, italian sweet red peppers, muscadine grapes, european plums, and blackcurrants. Pyridoxal 5'-phosphate, with regard to humans, has been found to be associated with several diseases such as epilepsy, early-onset, vitamin B6-dependent, odontohypophosphatasia, pyridoxamine 5-prime-phosphate oxidase deficiency, and hypophosphatasia. Pyridoxal 5'-phosphate has also been linked to the inborn metabolic disorder celiac disease.
