So that is the Xymogen form. And to actually activate our molecule, to activate our protein, another protein known as trypsin has to actually cleave or break a single peptide bond within that zymogen. So we have a Chimotryptinogen that basically reacts with our trypsin and the trypsin essentially cleaves our polypeptide chain along a single polypept or along a single bond shown here. And then we transform the Chimotryptin into the active enzyme known as Pychiamitrypsin. And then when Pi Chimotrypsin reacts with another Pi Chimotrypsin, we cleave it at yet another location. So basically, we remove two dipeptides from this location and this location and we form the final active molecule, our chimotryptin.
