## Abstract The stability of some Schiff‐bases formed between PLP and different amino acids has been investigated in a wide range of pH. The kinetic constants of formation of these compounds and their hydrolysis rate constants have been determined. Results show that the α‐position of the carboxyl g
We determined the apparent equilibrium constant of formation, KpH, of the Schijf bases of pyridoxal 5'-phosphate (PLP) and poly-and copolymers containing L-lysine, as a function of pH at 25" and a constant ionic strength of 0 . 1 ~. The KPH values obtained at acidic and neutral pH were larger that t
