Product name: Pyridoxal-5-phosphate Monohydrate / vitamin b6 powder , b6 vitamin
Pyridoxal-5’-phosphate monohydrate is a vitamin B6 metabolite that can modify lysyl and valyl residues in proteins. It has the ability to inhibit purinergic receptors and intracellular influx of Ca2+. Pyridoxal-5’-phosphate monohydrate can modify peptides and suppress their precursor ionization efficiency. Research shows that pyridoxal-5'-phosphate-dependent enzymes can be inhibited by cycloserine.
Pyridoxal phosphate (PLP, pyridoxal 5'-phosphate, P5P), the active form of vitamin B6, is a coenzyme in a variety of enzymatic reactions. The Enzyme commission has catalogued more than 140 PLP-dependent activities, corresponding to ~4% of all classified activities.[4] The versatility of PLP arises from its ability to covalently bind the substrate, and then to act as an electrophilic catalyst, thereby stabilizing different types of carbanionic reaction intermediates.
