09853 IUPAC Gold Book - plasma lipoproteins 10.1351/goldbook.09853 09853 current mentioned: high density lipoproteins (HDL), intermediate lipoproteins (IDL), low density lipoproteins (LDL), very low density lipoproteins (VLDL) 1 Assemblies of lipids and proteins in blood plasma transporting lipids between tissues. They are structurally very similar to intracellular lipid droplets. They are classified according to their size and buoyant density into five types with different functions: chylomicrons, very low density lipoproteins (VLDL), intermediate lipoproteins (IDL), low density lipoproteins (LDL), and high density lipoproteins (HDL).
