Definition: This is the active form of VITAMIN B 6 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).
deficiency: coordinate PYRIDOXAL PHOSPHATE /defic (IM) with VITAMIN B 6 DEFICIENCY (IM)
pyridoxal phosphate-6-azophenyl-2',4'-disulfonic acid [ PPADS ] a novel antagonist that selectively blocks P2 purinoceptor receptors; a useful tool to study co-transmission in tissues when ATP and coexisting neurotransmitters act in concert
