Web3 Jul 2024 · Trypsin and chymotrypsin are usually isolated from porcine or bovine pancreas. That is why these enzymes are frequently obtained as a mixture. Pancreatin, a powdery extract derived from porcine pancreas, more rarely from bovine pancreas, comprises a complex mixture of lipases, amylases and various proteases as the main ingredients. WebChymotrypsin, acyl-enzyme intermediate Transition-state stabilization in chymotrypsin also involves the side chains of the substrate. The side chain of the departing amine product forms stronger interactions with the enzyme upon formation of the tetrahedral intermediate.When the tetrahedral intermediate breaks down (Figure 16.24d and e), steric …
