<unk>  has been associated with the progression of atherosclerosis and blockage of the artery lumen, because it can carry cholesterol into smaller vessels. But<unk>  is also essential for carrying lipids that keep the human body alive, including in those small vessels.<unk>  <unk>  is one of the five major groups of lipoprotein which transport all fat molecules around the body in the extracellular water. These groups, from least dense to most dense, are chylomicrons (aka ULDL by the overall<unk>  naming convention), very<unk>  <unk> , intermediate-density lipoprotein (IDL),<unk>  <unk>  and high-density lipoprotein (HDL).<unk>  delivers fat molecules to cells.<unk>  is involved in atherosclerosis, a process in which it is oxidized within the walls of arteries.
