Substance Name: Pyridoxal phosphate [JAN]
RN: 41468-25-1
UNII: 5V5IOJ8338
InChIKey: CEEQUQSGVRRXQI-UHFFFAOYSA-N

Note

  • 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).
