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.

The metabolism of LP is controlled by their apolipoproteins, by specific receptors, enzymes, and transfer proteins.

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.
