WebMar 31, 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. WebJun 10, 2024 · The secondary structure of pepsin was unfolded with the treatment of nano-TiO (2) at pH 6.5 and pH 3.53, which might consequently affect the beta-hairpin loop that protects the active center of pepsin, and then reduce the enzyme activity.
