Ph of trypsin

WebMar 4, 2024 · In 1876, trypsin was first named by Kuhne who described the proteolytic activity of this pancreatic enzyme. He compared trypsin and pepsin, discovering the differentiating factor to be the optimal pH.

WebThe experiments of Table II show that after the casein has been exposed to concentrated solutions of trypsin (0.6 to 4 per cent) for a short time (10 minutes) no clot occurs. If rennin is subsequently added to this solution, no clot can be obtained since the trypsin has completely changed the casein molecule or complex.

Is the optimal pH of trypsin acidic or basic? - Answers

WebJul 22, 2024 · Catalysis mechanism: Pepsin is an aspartic protease which uses a catalytic aspartate in its active site, while trypsin is a serine protease employing the serine residue in active site.
