Pyridoxal-5-phosphate is the biologically active form of vitamin B6 and serves as a coenzyme in various enzymatic reactions in the body, primarily in amino acid metabolism. In research, it is utilized to investigate its role in transamination, decarboxylation, and racemization reactions of amino acids. Pyridoxal-5-phosphate is essential in the study of enzymatic mechanisms where it forms a Schiff base with the amino group of amino acids, facilitating a variety of biochemical transformations. Its involvement in the synthesis of neurotransmitters, such as serotonin and gamma-aminobutyric acid (GABA), also makes it a key compound in neuroscience research. Additionally, Pyridoxal-5-phosphate is used to explore its role in glycogen phosphorylase function, which is important for understanding glucose metabolism and energy production in cells.
