In medicine and biochemistry, lipoproteins are "lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of triglycerides and cholesterol esters surrounded by a layer of hydrophilic free cholesterol; phospholipids; and apolipoproteins. Lipoproteins are classified by their varying buoyant density and sizes. The large lipoproteins (chylomicrons; VLDL) are to transport triglycerides, and the small lipoproteins (LDL; HDL) are to transport cholesterol."[1]
