title: Lipoprotein charge and vascular lipid metabolism.
abstract: Lipoproteins play a central role in transporting hydrophobic molecules through the bloodstream and between specific tissues. Lipoprotein molecules have a distinctive electrical charge and changes in electrostatic properties directly affect the metabolism of the lipoprotein. Lipoprotein charge controls interfacial interactions and determines the ability of the lipoprotein to interact with intravascular enzymes and cell surface proteins. Uniquely charged constituents of the lipoprotein thereby control the metabolism of lipoproteins by creating a regulatory system wherein the electrostatic properties of plasma lipoproteins determine the fate of intravascular lipids.
