Web9 de jun. de 2024 · The two major pancreatic enzymes that digest proteins are trypsin and chymotrypsin. Amino acids, dipeptides, and tripeptides are absorbed into the cells of the intestinal wall. The cells that line the small intestine release peptidases (enzymes) that break down dipeptides and tripeptides into single amino acids. WebOnce absorbed carbohydrates pass through the liver, glucose is the main form of carbohydrate circulating in the bloodstream. 4 – Large Intestine or Colon. Any carbohydrates that weren’t digested in the small intestine—mainly fiber—pass into the large intestine, but there’s no enzymatic digestion of these carbohydrates here.

WebFigure 5.22. Lipid digestion and absorption in the small intestine. Once inside the intestinal cell, short- and medium-chain fatty acids and glycerol can be directly absorbed into the bloodstream, but larger lipids such as long-chain fatty acids, monoglycerides, fat-soluble vitamins, and cholesterol need help with absorption and transport to the bloodstream.
