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. how do i make bbc my home page on windows 10WebNational Center for Biotechnology Information how do i make bbc news my home page in edgeWebPepsinogen undergoes autocatalytic cleavage at an optimum pH of 1.5 to 2, forming the active pepsin molecule, which, in turn, can activate additional molecules of pepsinogen. … how do i make arroz con lecheWebFeb 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.
