title: Nuclear magnetic resonance spectroscopic studies of interaction of bis-GMA analogues with phosphatidylcholine liposomes as a model for biomembranes.
abstract: The interaction of bis-GMA analogues with dipalmitoylphosphatidylcholine liposomes was studied by 1H and 13C nuclear magnetic resonance spectroscopy. It was found that bis-GMA analogues did not diffuse from liposomes once they were incorporated into the lipid bilayers of dipalmitoylphosphatidylcholine. The mobility of iso-bis-GMA was strongly disturbed by dipalmitoylphosphatidylcholine. The large changes in nuclear magnetic resonance spectra of iso-bis-GMA indicated that the interaction of iso-bis-GMA with dipalmitylphosphatidylcholine was larger than that of bis-GMA. This seems to be due to the chemical structure of iso-bis-GMA with the primary hydroxyl group.
