Lipids, lipoproteins and apolipoproteins

Each primary lipoprotein is characterized by the presence in its composition of an individual, only inherent protein (apolipoprotein). Apolipoproteins are denoted in Latin letters, some of which are a family of proteins and are also indicated by numbers (for example, apo-A1, apo-A2, etc.).

Lipoprotein of blood plasma - the transport form of lipids in the human body. They carry the transport of lipids as exogenous (food), and endogenous origin. Individual lipoproteins capture excess cholesterol from cells of peripheral tissues to transport it to the liver, where it is oxidized to bile acids and excretion with bile.

High-density lipoprotein cholesterol (HDL-cholesterol) is defined as the remaining amount of cholesterol in the blood serum after the deposition of apo-B-containing lipoproteins (low and very low density lipoproteins).
