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. WebMar 4, 2024 · The lymphatic system is a system similar to the circulatory system in that it contains vessels that transport fluid.

WebThe vitamins A, D, E, and K known as the fat-soluble vitamins are soluble in lipids and are absorbed simultaneously with fats from the diet. After being absorbed, they are then packed into chylomicrons, which are lipoprotein particles that transport lipids and fat-soluble vitamins from the small intestine into the lymphatic system.

WebChylomicrons. Chylomicrons are the largest and most buoyant class of lipoprotein. The major protein component is apo B-48 but they also contain apo A-I, apo A-II and apo A-IV. After secretion, they acquire apo E and apo C from HDL. Chylomicrons are formed in the intestine and are the transport vehicle for dietary fat. 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…
