How is enzyme activity affected by ph

WebEnzyme activity and stability depend strongly on the pH value of the reaction solution. The active sites of enzyme consist of amino acids with some ionic groups, such as carboxyl group, amino group, thiol group, imidazole group, phenolic hydroxyl group, and so on.
