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 cleaves peptide bonds in the amino-terminal side of the cyclic amino acid residues (tyrosine, phenylalanine, and tryptophan), breaking the polypeptide chains into smaller peptides (Fange and Grove, 1979).
Detailed explanation-3: -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-4: -Protease (made in the pancreas; breaks down proteins)
Detailed explanation-5: -*Pepsin acts on protein and converts them into proteoses and peptones, trypsin acts on proteoses and peptones and converts them into polypeptides.
