| 中文摘要 | the interactions of lanthanide ions and the ln-dtpa (dtpa = diethylenetriaminepentaacetate) complex with di palmitoylphosphatidylcholine (dppc) and dipalmitoylphosphatidylethanolamine (dppe) bilayers are studied by 2d noesy and ft-raman spectroscopy. proton nmr spectroscopic results show that lanthanide ions combine with phosphate groups in the polar region of the outer layer of dppc liposomes, leading to the separation in chemical shift of the proton signal of n(ch3)(3) the conformational change of the o-c-c-n+ backbone from the gauche conformer to the trans one is not found; i.e., the orientation of the polar headgroup is still parallel to the surface of the bilayers. the ln-dtpa complex at low concentration in a ph 7.4 solution localizes far away from bilayers and thereby has little effect on the structure of bilayers. the ft-raman spectroscopic results indicate that lanthanide ions affect strongly the fluidity of acyl chains of dppe bilayers while the ln-dtpa complex affects it slightly. |
