Optimum temperature of pepsin
WebTable 1 shows that at 10°c, 20°c and 30°c the light absorbed by the solution is more than at 40°c, this is because the pepsin has not broken down as much of the egg albumen at … WebPepsin is stable over the pH range of 1–6 ( 3 ). Above pH 6, pepsin is rapidly irreversibly inactivated. At pH 8 pepsin is completely inactivated ( 3, 20 ). Pepsin has a maximum activity at pH 2 ...
Optimum temperature of pepsin
Did you know?
WebTo prevent self-digestion, pepsins need to be stored at very low temperatures that range between −80°C and −20°C. Pepsin hydrolyzes the peptide bonds of proteins, breaking them down into smaller polypeptide fragments. It is active under the acidic conditions that are provided by the presence of gastric juice in the stomach. WebThe optimum reaction temperature for pepsin was determined to be 60°C, and after incubation at 60°C for 30 min, the enzyme still retained more than 50% of its peak activity, indicating the rigidity of the pepsin structure. The results of the set of mutations provided by energy-based prediction software programs confirmed this result.
