1. The outside-inside distribution of palmitoyl lysophosphatidylcholine and dioleoyl phosphatidylcholine in mixed sonicated vesicles is measured with (N-13CH3)-labelled lipids using 13C NMR and Dy3+ as an impermeable shift reagent. 2.

(2) In the liquid crystalline state the 31 P NMR liposome spectra are similar for both saturated and unsaturated phosphatidylcholines, demonstrating that the motion of the polar headgroup is not sensitive to the fatty acid composition in the disordered liquid crystalline state.
