Explanation

The majority of protein digestion occurs in the duodenum, the first segment of the small intestine. In the duodenum, pancreatic enzymes, such as trypsin, chymotrypsin, and peptidases, break down polypeptides into smaller peptides and individual amino acids. This process allows for the complete digestion of proteins.
