VLDLs and LDLs are successively denser, having higher ratios of protein to lipid. HDL particles are the densest.Composition of the lipoproteinsLipoproteinSourceDiameter (nm)Density (g/mL)CompositionMain Lipid ComponentsApolipoproteinsProtein (%)LipidChylomicronsIntestine90-1000<0.951-298-99TriacylglycerolA-I, A-II, A-IV,l B-48, C-I, C-II, C-III, EChylomicron remnantsChylomicrons45-150< 1.0056-892-94Triacylglycerol, phospholipids,cholesterolB-48, EVLDLLiver (intestine)30-900.95-1.0067-1090-93TriacylglycerolB-100, C-I, C-II, C-IIIIDLVLDL25-351.006-1.0191189Triacylglycerol, cholesterolB-100, ELDLVLDL20-251.019-1.0632179CholesterolB-100HDLLiver, intestine,VLDL, chylomicrons20-251.019-1.0633268Phospholipids, cholesterolA-I, A-II, A-IV, C-I, C-II, C-III, D,2 EHDL1HDL210-201.063-1.1253367HDL35-101.125-1.2105743PreP-HDL3<5>1.210 A-IAlbumin/free fatty acidsAdipose tissue >1.28199-1Free fatty acids 1 Secreted with chylomicrons but transfers to HDL.Associated with HDL2 and HDL3 subtractions.3Part of a minor fraction known as very high density lipoproteins (VHDL).
