chylomicron

…the blood are known as chylomicrons and consist largely of triglycerides; after absorption from the intestine, they pass through lymphatic channels and enter the bloodstream through the thoracic lymph duct. The other plasma lipids are derived from food or enter the plasma from tissue sites.

Chylomicrons are the largest lipoproteins, with diameters of 75–600 nm (1 nm = 10⁻⁹ meter). They have the lowest protein-to-lipid ratio (being about 90 percent lipid) and therefore the lowest density. Chylomicrons are synthesized by the absorptive cells of the intestinal lining and are…

…are packaged into vesicles (chylomicrons). These vesicles are spheres with an outer coating of phospholipids and a small amount of apoprotein, while the interior is entirely triglyceride except for a small quantity of cholesterol. The chylomicrons migrate to the cell membrane, pass through it, and are attracted into the…
