Lipoproteins. Computer illustration showing the comparative sizes and structure of different lipoprotein particles. From top left to right: High-density lipoprotein (HDL),low-density lipoprotein (LDL),very low-density lipoprotein (VLDL) and chylomicron. Lipoproteins are the major carriers of cholesterol in the blood and are mainly composed of lipids (fats). The complex structure includes carrier proteins (exterior 'ribbons') known as apo-B proteins,which assist transport in the blood. The outer coat consists of phospholipids (purple spheres) and free cholesterol molecules. Within the core cholesterol molecules are bound into long esters by fatty acid chains | |
