Apolipoproteins (Apos) are important protein components of lipoprotein particles. They participate in the transport of triglycerides, cholesterol, phospholipids, and lipid-soluble molecules, and determine the interactions between lipoproteins and receptors, enzymes, and transport proteins.
Lipoproteins are spherical particles composed of a hydrophobic lipid core and a hydrophilic surface shell. The core is enriched in hydrophobic lipids such as cholesteryl esters and triglycerides, whereas the surface is formed by phospholipids, free cholesterol, and apolipoproteins, enabling ...
