WebThe optimum pH for alpha-Amylase is 6.9 – 7.0. Deviation within this range tends to alter the functionality of the amylase and extreme alkaline condition (say pH 11, as mentioned by Mr. Sivamani) will cause complete denaturation. Is amylase an acid? It has a pH of 2 to 3, meaning it is acidic like vinegar. 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. Web1) Optimal pH for the digestion of starch by amylase is 7.0 - 8.0.
