title: Reactions of oxidized lipids with protein. XIII. Interactions of polar groups of lipids with nonlipidic substances.
abstract: Contrary to fresh lipids, oxidized lipids form chloroform-insoluble, but methanol-soluble compounds with cellulose. The amount of chloroform-insoluble lipids is significantly higher in mixtures containing cellulose impregnated with albumin. Polar groups of oxidized lipids formed nonextractable compounds with protein more readily than polar groups of a monoglyceride. Compounds insoluble either in chloroform and in chloroform-methanol or methanol were formed in contact of oxidized lipids with protein, contrary to mixtures of lipids with sole cellulose. The formation of these nonextractable compounds is due both to the interaction of protein with hydroperoxides and with non-peroxidic oxidation products.
