But because of a small localized change in this section of that enzyme that creates a perfect active that can fit the substrate molecule and also creates the oxygen hole that will be used by the Chimetrypsin to basically stabilize and decrease that transition state that is formed in that proteolytic reaction that is carried out that is carried out by the digestive enzyme climate trypsin. Now, this is only one of the many different types of digestive enzymes that exist inside our body. And the reason we have these different digestive enzymes is because each digestive enzyme has a slightly different specificity. And we need all these different enzymes to be able to cleave all the different peptide bonds that are found within the proteins that we actually ingest. And the interesting thing about the trypsin molecule that we discussed earlier, trypsin doesn't only activate the chinatriptcinogen, it also activates many other zymogens. And so in a way, we can imagine that trypsin is actually the master activator which is responsible for actually activating the majority of the xiaogens found inside our body.
