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).
