  • Title: Interactions of ferrous ions with peroxidized lecithin-liposomes.
    Author: Kowalska E, Naglik T.
    Journal: Acta Biochim Pol; 1990; 37(1):85-8. PubMed ID: 2087921.
    Abstract:
    Oxidation of Fe2+ in the presence of peroxidized lecithin-liposomes small unilamellar vesicles suspended in various media (pH = 5.5) is described. Peroxidation of lecithin was induced by UV light and assayed by three methods: estimation of conjugated dienes, accumulation of hydroperoxides and by the thiobarbituric acid test. The oxidation of Fe2+ was accelerated by phosphate and citrate buffers, but in acetate buffer it was dependent on lipid peroxidases concentration and exhibited saturation kinetics.
