ANATOMY

Detailed explanation-1: -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-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: -Proteins are digested in the stomach and duodenum of the small intestine. The main enzymes that catalyze protein digestion are pepsin secreted in the stomach and trypsin, chymotrypsin, and carboxypeptidase secreted from the pancreas.

Detailed explanation-4: -Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins.
