Differential scanning calorimetry characterization of oxidized egg phosphatidylcholine liposomes.
Differential scanning calorimetry has been used to characterize liposomes made from mixtures of unoxidized and singlet oxygen oxidized egg phosphatidylcholine. Cooling scans reveal that trapped water decreases when the oxidized phosphatidylcholine content is increased in the liposomes. Liposomes made from mixtures containing more than 50% by weight of oxidized phosphatidylcholine do not show trapped water.
