The optimum ph for amylase activity is
Web• The optimum pH level for salivary amylase is approximately 6.8. Any change of pH below or above the optimum pH decreases the rate of enzyme action. The changes in pH can lead to changes in the ionization state of the substrate or the enzyme or both. The optimal pH level is slightly acidic whereas the enzyme is a little more basic. 2.
