Apolipoproteins
apolipoproteins
Protein or apolipoprotein associated with High-Density Lipoproteins (HDL), a class of proteins involved in lipid (cholesterol, phospholipids and triacylglycerol) metabolism in the body fluids. HDL are formed in the liver and are involved in reverse cholesterol transport, the transport of cholesterol from peripherical tissues to the liver. Apolipoproteins are proteins which are specifically associated with lipoproteins, which is not the case for all the proteins associated with HDL or with the other lipoprotein classes.
