ANATOMY

Detailed explanation-1: -Digestion of proteins starts in stomach by the action of gastric juice produced by the walls of the stomach. Digestion of protein also takes place in duodenum and ileum by the action of pancreatic and intestinal juice .

Detailed explanation-2: -Protein is a vital nutrient for almost every part of your body. It’s digested in your mouth, stomach, and small intestine before it’s released into your bloodstream as individual amino acids.

Detailed explanation-3: -Protein starts to break down in the stomach. Absorption of protein starts in duodenum which breakdowns protein into smaller forms called amino acids and these amino acids are finally absorbed by ileum and then they are used by different parts of the body via blood.

Detailed explanation-4: -The two major pancreatic enzymes that digest proteins in the small intestine are chymotrypsin and trypsin . Trypsin activates other protein-digesting enzymes called proteases, and together, these enzymes break proteins down to tripeptides, dipeptides, and individual amino acids.
