WebThe chirality of an amino acid is determined during transamination. For the reaction to complete, aminotransferases require participation of aldehyde containing coenzyme, pyridoxal-5'-phosphate (PLP), a derivative of Pyridoxine (Vitamin B 6). The amino group is accommodated by conversion of this coenzyme to pyridoxamine-5'-phosphate (PMP). WebEllman's Sulfinamides.
