Transportation of Lipids in Blood
Chylomicrons
-Phospholipids, cholesterol and triglycerides combine with
protein to form chylomicrons.
-90% triglyceride, 4% phospholipid, 1% protein, 5%
cholesterol, apo E.
-Excreted into lacteals and circulate into the blood via
thoracic duct (lacteals -> lymphatic vessels -> thoracic
duct -> left subclavian vein).
-Bind to receptors in membrane of endothelial cells in
capillaries of muscle and adipose tissue.
