13C nuclear magnetic resonance studies of egg phosphatidylcholine.
Spin lattice relaxation times (T1) and apparent spin-spin relaxation times (T2) derived from linewidth have been used to investigate model membranes composed of egg yolk phosphatidylcholine. T1 measurements appear to be largely dominated by segmental motion and as a consequence are not very sensitive to small changes in membrane structure. On the contrary, apparent T2 times are shown to be sensitive to such changes in the membrane and are thus suggested as a useful tool for further investigation of membrane structure.
