Formed as VLDL become depleted in TG; either returned to liver or … 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…

WebFirst of all, I think this video was a bit misleading in describing the structure of the chylomicron, which is only about 1-2% protein. Most of it is made of triglycerides, phospholipids, and cholesterol. Still though, the idea is that the outside of the chylomicron is polar, which allows it to be soluble in polar substances like plasma and lymph. WebBecause fat and water do not mix well, and blood is 50% water, fat must be transported on structures that can bridge the fat-water barrier. These structures are called lipoproteins. Lipoproteins are composed of phospholipids, fatty acids, cholesterol and proteins and transport the lipids through the lymphatic and circulatory systems.
