Four major groups of lipoproteins have been identified that are important physiologically and in clinical diagnosis. These are,

Chylomicrons, derived from intestinal absorption of triacylglycerol and other lipids.
Very low density lipoproteins (VLDL), derived from the liver for the export of triacylglycerol.
Low-density lipoproteins (LDL), representing a final stage in the catabolism of VLDL. 
High-density lipoproteins (HDL), involved in cholesterol transport and also in VLDL and chylomicron metabolism. Triacylglycerol is the predominant lipid in chylomicrons and VLDL, whereas cholesterol and phospholipid are the predominant lipids in LDL and HDL, respectively.
