Chylomicrons Large droplets of lipid sealed into a shell of cholesterol, protein, and phospholipid Protects the very hydrophobic lipids from blood Mostly triglyceride This bubble of lipid now leaves the mucosal cell and goes out into the lymphatic  system, eventually joining up with the bloodstream, where it delivers triglyceride  to the hungry body Lipoprotein lipase - enzyme attached to artery wall   breaks down triglyceride  into free fatty acids and glycerol   nearby muscle, adipose, and other cells take  up these nutrients and put them to use Chylomicrons roam the arteries for several hours after a meal until all their  triglyceride is delivered   little is left but the shell and cholesterol, which return to  the liver Very Low Density Lipoproteins (VLDL) The liver synthesizes cholesterol needed by the body Also synthesizes triglyceride out of of excess carbs and protein The liver packages these  endogenous  (made within the body) lipids, along with  dietary cholesterol left over from the chylomicrons, into  Very Low Density
