Importance
The process of LDL formation begins when intrahepatic cholesterol is repackaged by the liver into VLDL (Very Low-density lipoprotein). VLDL then enters the circulation and is converted by lipoprotein lipase and cholesteryl ester transfer protein (CETP) into more cholesterolenriched species, first IDL (Intermediate-density lipoprotein) and then LDL (Wadhera et al., 2015).
Circulating LDL particles are able to penetrate the endothelium of arterial walls and become oxidized, promote inflammation, and drive injury to the overlying endothelium and surrounding smooth muscle cells (Ross, 1999).
