Radiation Chemistry


The effect of Ca2+ ions on the radiation-initiated reaction of free-radical fragmentation of dimyristoyl phosphatidylglycerol arranged as monolamellar and multilamellar liposomes was examined. It was found that the formation of the reaction products dimyristoyl phosphatidic acid and hydroxy acetone was considerably reduced in the presence of Ca2+ ions at all γ-irradiation doses examined regardless of the type of model membranes.
