Pyridoxine-5'-phosphate is involved in many reactions in the body, including protein synthesis and metabolism. It is required for glucocorticoid receptor activation and transcriptional regulation. It may also play a role in growth factor-β1 production and its role in cell signaling pathways. The deficiency of this vitamin causes symptoms such as weakness, irritability, depression, apathy, memory loss, hallucinations or convulsions.
