Optimal ph for salivary amylase

WebThe optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denaturated. The enzyme salivary amylase is most active at pH 6.8. Our stomach has high level of acidity which causes the salivary amylase to denature and change its shape. 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 pHcan 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.
