DrugBank ID	DB00114
Name	Pyridoxal phosphate
Groups	investigational nutraceutical approved
Description	This is the active form of vitamin B6 serving as a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into pyridoxamine phosphate (pyridoxamine).
