"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… " - How are chylomicrons transported

WebThe function of Chylomicron is to transports exogenous lipids to the liver, fat, heart, and skeletal muscle tissue. At these locations, the activity of lipoprotein lipase lowers triglycerides. When most of the core of triacylglycerol has been hydrolyzed, its residues form and transfer to the liver. WebChylomicrons enter the portal system and interact with lipoprotein lipase (LPL) on the surface of muscle cells or adipose cells. LPL separates all three fatty acids from glycerol. Fatty acids can be used as a source of energy by muscle cells or be stored in adipose tissue in the form of TG.
