WebEach polypeptide chain is made up of smaller subunits or amino acids bonded together. Polypeptides are the building blocks of proteins, and amino acids are the building units of polypeptides. Consider a single amino acid as a paper clip. A paper clip chain is formed by joining numerous paper clips together. WebProtein breakdown (digestion) into amino acids begins with mastication (chewing the food). After the food is ground down it passes through the esophagus and into the stomach. There, mucus, hydrochloric acid and pepsinogen all mix with and chemically start to break down the complex proteins. The hydrochloric acid and the pepsinogen combine to ...
