Lipoproteins

These are the compound lipids found in plasma and cell membrane. The lipid constituents of lipoproteins are mostly esterified cholesterol and phosholipids. The most important role of lipoproteins in the body is to transport and deliver the lipids to tissue and to maintain the structural integrity of cell surface and subcellular particles like mitochondria and microsomes. The four major groups have been identified
a) Chylomicrons
b) Very Low Density Lipoproteins
c) Low Density Lipoproteins
d) High Density Lipoproteins
