HUMAN NUTRITION

Detailed explanation-1: -An enzyme made in the stomach that breaks down proteins in food during digestion. Stomach acid changes a protein called pepsinogen into pepsin.

Detailed explanation-2: -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-3: -Protease (made in the pancreas; breaks down proteins)

Detailed explanation-4: -Pepsin /ˈpɛpsɪn/ is an endopeptidase that breaks down proteins into smaller peptides. It is produced in the gastric chief cells of the stomach lining and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

Detailed explanation-5: -The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids. In the duodenum, other enzymes-trypsin, elastase, and chymotrypsin-act on the peptides reducing them to smaller peptides.
