The core principle governing lipid transport dynamics is that Very Low Density Lipoprotein (VLDL), secreted by the liver and bearing Apolipoprotein B100, undergoes lipolytic conversion to Intermediate-Density Lipoprotein (IDL) and subsequently Low-Density Lipoprotein (LDL). This transformation facilitates the directional delivery of triglycerides and cholesterol from hepatic storage sites to peripheral tissues via LDL receptor-mediated endocytosis. Simultaneously, Apolipoprotein A1 activates Lecithin-Cholesterol Acyltransferase (LCAT) on nascent High-Density Lipoprotein (HDL), enabling its function in the reverse transport of lipids from peripheral cells back to the liver for hepatic delivery and metabolic clearance.
