This video gives a comprehensive description of lipoproteins and their biological importance.A lipoprotein is a biochemical assembly whose primary purpose is to transport hydrophobic lipid (also known as fat) molecules in water, as in blood plasma or other extracellular fluids.Examples of lipoproteins include plasma lipoprotein particles (HDL, LDL, IDL, VLDL and chylomicrons). Subgroups of these plasma particles are primary drivers or modulators of atherosclerosis.
