Pancreatic lipases digest dietary triglycerides in the lumen of the small intestine, forming monoglycerides and fatty acids. These lipids are absorbed into enterocytes via passive diffusion. Inside the cell, these lipids are transported to the smooth endoplasmic reticulum, where they are re-esterified to form triglycerides. These triglycerides, along with phospholipids and cholesterol, are added to apolipoprotein B48 to form immature chylomicrons. Immature chylomicrons are tran… WebFeb 18, 2024 · A chylomicron (Figure \(\PageIndex{3b}\)) is a large lipoprotein that is used to transport fat from a meal.

WebThe vitamins A, D, E, and K known as the fat-soluble vitamins are soluble in lipids and are absorbed simultaneously with fats from the diet. After being absorbed, they are then packed into chylomicrons, which are lipoprotein particles that transport lipids and fat-soluble vitamins from the small intestine into the lymphatic system. WebThe mechanism of fat-induced LPS absorption is unclear, however. Intestinal-epithelial cells can internalize LPS from the apical surface and transport LPS to the Golgi. The Golgi complex also contains newly formed chylomicrons, the lipoproteins that transport dietary long-chain fat through mesenteric lymph and blood.
