[Changes in the surface charge of plasma lipoproteins during their auto-oxidation].
Low density lipoproteins (LDL) and high density lipoproteins (HDL) surface potential (charge) changes were studied upon autooxidation, using positively charged spin probes. Lipid peroxidation product accumulation in LDL and HDL suspensions was found to be accompanied by a significant reduction in their surface area associated with a decreased negative surface charge, and probably, deposition of lipid peroxidation polar products and/or surface charge redistribution as a result of lipoprotein autooxidative modification.
