«Very-low-density lipoprotein (VLDL), density relative to extracellular water, is a type of lipoprotein made by the liver.[1] VLDL is one of the five major groups of lipoproteins (chylomicrons, VLDL, intermediate-density lipoprotein, low-density lipoprotein, high-density lipoprotein) that enable fat and cholesterol to move within the water-based solution of the bloodstream. VLDL is assembled in the liver from triglyceride, cholesterol, and apolipoproteins. VLDL is converted in the bloodstream to low-density lipoprotein (LDL) and intermediate-density lipoprotein (IDL). VLDL particles have a diameter of 30–80 nm. VLDL transports endogenous products, whereas chylomicrons transport exogenous (dietary) products. Recently both the lipid composition [2] and protein composition [3] of this lipoprotein were characterised in great detail.» (wikipedia)
