[Electric stability of liposome membranes in UV-induced lipid peroxidation].
It has been shown that UV-induced peroxide oxidation of lipids (POL) and its water-soluble products similarly affect the liposomes of egg lecithin and mitochondrial lipids; they decrease the electric stability of the membranes, and aggregation ability of vesicles and increase proton permeability of the membranes. Possible mechanism of the increase of membrane ionic permeability during POL is discussed.
