Abstract
The hydrolytic degradation of hyaluronic acid (HA) was investigated by kinetic measurements. The first-order rate constants of the hydrolyti c degradation of HA at different pH and temperature were obtained on t he basis of the decrease in the molecular weight of HA. In addition, f rom the rate constant, we obtained the activation entropy (Delta S) a nd enthalpy (Delta H), and under all conditions studied the experimen tal data gave linear plots according to an isokinetic relationship.
