I expected that pepsin will destroy the structure of gelatin protein, because the pepsin broke down the primary structure of the gelatin polypeptide into amino acid monomers. The hydrochloric acid (HCL) expected to affect the ability of amylase to digest starch, because as it is an acid it effects on the protein that makes it unraveled as it breaks down the secondary structure which it contains hydrogen bonds. As I have done to experiment one titled Digestion of Proteins by Pepsin. The result was the tube that has pepsin would digest as the pepsin destroyed the gelatin's the primary structure, but it got solid in the tube that has water in as nothing destroyed the gelatin polypeptide. Meanwhile, the other experiment that titled Digestion of
