WebAug 22, 2016 · Most enzymes' optimum pH is neutral or close to neutral, like amylase found in saliva, which has an optimal pH = 6.8. Some enzymes prefer a more drastic pH, like … WebpH Each enzyme has an optimal pH. A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule change and the molecule changes shape. The new shape may not be effective. The diagram below shows that pepsin functions best in an acid environment.

A substance that helps a chemical reaction to occur is a catalyst, and the special molecules that catalyze biochemical reactions are enzymes. Almost all enzymes are proteins, comprised of amino acid chains. Enzymes facilitate chemical reactions by binding to the reactant molecules, and holding them in such a way as to make the ... WebWhen pH of a particular medium changes, it leads to an alteration in the shape of the enzyme. Not only enzymes, the pH level may also affect the charge and shape of the substrate.
