Lipid Transport from the Liver The contents of chylomicron remnants, as well as other lipids in the liver, are incorporated into another type of lipoprotein called very-low-density lipoprotein (VLDL). 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… curles neck dairy milk bottle
