ANATOMY

Detailed explanation-1: -It’s digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.

Detailed explanation-2: -Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Detailed explanation-3: -Digestion of protein starts in stomach of human digestive tract. When we consume food, digestion is a crucial process that must occur at regular intervals. Digestion necessitates the use of specialised enzymes that act on specific compounds. The enzyme pepsin is responsible for the digestion of proteins.

Detailed explanation-4: -The stomach empties the chyme containing the broken down egg pieces into the small intestine, where the majority of protein digestion occurs. The pancreas secretes digestive juice that contains more enzymes that further break down the protein fragments.

Detailed explanation-5: -Protein digestion continues in the stomach where HCl denatures the proteins and pepsin breaks apart the bonds that hold the protein together. Protein digestion ends in the small intestine where carboxypeptidase, trypsin and chymotrypsin continue to break the peptide bonds until only amino acids remain.
