The largest lipoproteins produced by intestinal epithelial cells from dietary fats are chylomicrons. These lipoproteins can range in diameter from 75 to 1,200 nanometers, making them the largest class of lipoproteins. Chylomicrons are primarily responsible for transporting dietary triglycerides, cholesterol, and fat-soluble vitamins from the intestines to other tissues in the body. They are formed in the enterocytes of the intestinal lining after the absorption of dietary lipids.
