VLDL-remnant and Chylomicron (CM) remnant, these two types of remnants are known. Those are the intermediate metabolites of very low-density lipoprotein (VLDL) and CM, respectively.The remnant lipoproteins are usually metabolized very quickly. However, since the remnants are easily phagocytosed by macrophages, they are reported to be deeply involved in the pathogenesis and progress of arteriosclerosis and to be a risk factor of coronary artery disease, too.
