Detailed explanation-1: -Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine.
Detailed explanation-2: -Pepsin is a proteolytic enzyme, secreted as its precursor pepsinogen by chief cell of gastric pits of vertebrate stomach. It gets activated due to the acid (HCl) present in the stomach. It converts proteins into polypeptides.
Detailed explanation-3: -Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.
Detailed explanation-4: -The pancreas secretes digestive juice that contains proteases (enzymes) that break down polypeptides into smaller peptides or single amino acids. The two major pancreatic enzymes that digest proteins are trypsin and chymotrypsin.
