摘要:
Comparison of the different methods to determine aliphatic chain length in biomembranes from the C-D quadrupolar splittings obtained with solid state H-2-NMR is reported. It is shown that perdeuteration of the saturated lipid acyl chains is the alternative to selectively labelled chains without loss of accuracy. Accuracy in chain length determination may be then estimated to be of the order of 0.2 Angstrom.
