WebFeb 17, 2024 · For example, trypsin and pepsin are both enzymes in the digestive system which break protein chains in the food into smaller bits - either into smaller peptide chains or into individual amino acids. Pepsin works in the highly acidic conditions of the stomach. It has an optimum pH of about 1.5. WebBackground: As you know from reviewing the Pepsin Report, pepsin is an enzyme that hydrolyzes the peptide bond of a substrate. As a result, the protein is cleaved into smaller units. The reaction (as is most enzyme reactions) is pH dependent. It is the purpose of this experiment to investigate the pH dependence of the pepsin reaction.
