Your body has a mechanism and set of enzymes for digesting the carbs, protein and fat molecules in your food. Chemical digestion occurs in several steps beginning in the mouth and ending with absorption in the small intestinal cells.
Often the final steps of digestion take place in the villi of enterocytes. These enzymes are almost all hydrolases. The digestion of carbohydrates begins in mouth by the salivary amylase and continues in the small intestine by pancreatic amylase and the intestinal and mucosal oligo-and disaccharidases.he proteolytic enzymes of the pancreas, i.e. trypsin, chymotrypsin and carboxypolipeptidase, which are also secreted in inactive forms, continue protein digestion. The end products of protein digestion are amino acids, produced by the action of intestinal and mucosal dipeptidases.
