Pyridoxal 5′-phosphate (PLP), the active form of vitamin B6, works as cofactor in numerous enzymatic reactions and it behaves as antioxidant molecule. Pyridoxal 5'-phosphate (P5P) is the active form of (vitamin B6), which is part of the B complex—a group of water-soluble vitamins that play important roles in cellular metabolism and energy production. Pharm. Yoo, J.Y. 3 Key Health Benefits of Vitamin B6 as Pyridoxal-5-Phosphate (P5P) Many people who are health conscious have likely heard of the benefits you can get from vitamin B6. Pyridoxal phosphate : pyridoxal phosphate is the active form of vitamin B6 is a coenzyme in a variety of enzymatic reactions. Brady, G.J. Meydani, J.D. Nutr. The term vitamin B6 refers to six forms—pyridoxal, pyridoxamine, pyridoxine, and their phosphorylated forms. Brady, G.J. The more common form of vitamin B6 used in dietary supplements, pyridoxine, must undergo metabolic transformation and requires ATP to be converted into P5P. Major food sources of vitamin B6 include whole grains, bananas, nuts and meat. Cell. Acad. [25]C.-H. Cheng, S.-J. The pyridoxine form requires ATP to be “activated.” In general, we think it’s a good idea to conserve ATP for more important uses in our cells and tissues. Aspy, N.A. Looking to order a test? Vitamin B6 is a complex of 6 vitamers: pyridoxal, pyridoxol, pyridoxamine, and their 5'-phosphate esters. Badawy, Int. Biochem. Rajeswari, E. Radha, Exp. Bull. Hansen, J.E.

From a less scientific standpoint, PLP can be used as a dietary supplement in cases of vitamin B6 deficiency, and reduced levels of PLP in the brain can cause neurologic dysfunction. PLP is required for over 100 different reactions in human metabolism, primarily in the various amino acid biosynthetic and degradation pathways. Wu, Y.-C. Huang, Eur. 283–299. 300–322. Skills 125 (2018) 451–462. J. Med. EU/UK Privacy Policy Pyridoxine is the "storage form" of vitamin B6, the kind that is found in whole grains, seeds, and other plant foods. 35 (2012) 532–538.

It is important to have sufficient amounts of vitamin B6 in the diet to allow proper functioning of these enzymes. Due to its role as a cofactor in a number of enzymatic reactions, pyridoxal phosphate (PLP) has been determined to be the biologically active form of vitamin B6. Leklem, K. Hardin, T.D. It also helps maintain normal brain function, being that it is required for the production of several vital neurotransmitters, as we touched on above. Tymoczko, G.J. Ribaya-Mercado, American Journal of … (1991). As such an important part of healthy functioning in the brain and body, P5P brings to the table a number of possible benefits, with two of the most noteworthy being: Beyond this, there are potential benefits to mention with regard to vitamin B6; different conditions may deplete one’s vitamin B6, triggering nerve damage and other deficiency symptoms. Price (Eds. Overview Information Vitamin B6 is a type of B vitamin. It also helps maintain normal brain function, being that it is required for the production of several vital neurotransmitters, as we touched on above. Vitamin B6 supplementation may help with: It may also prevent deficiency caused by the following drugs: We can almost never get enough vitamin B6 from food, but we can get too much of it in supplement form if it’s taken for too long a period (x). [34]A.D. Volpe, A.D. Lucia, C. Pirozzi, V. Pastore, J Int Adv Otol 13 (2017) 69–73. Nutr. Sci. Pyridoxine deficiency causes blood, skin and nerve changes, and what makes this unique is that either deficiency or excess can cause peripheral neuropathy. There are several compounds that are commonly referred to as B6 including Pyridoxine, Pyridoxal, Pyridoxamine, and their respective 5`-phosphate forms. [8]M.E. Experts suggest preventative supplementation in people suffering with digestive disorders (IBD, celiac disease et al), malnutrition, alcohol dependence and kidney failure (x) (xx) (xxx) (xxxx) (xxxxx).
