Conformation of the polar headgroup of sphingomyelin and its analogues.


The conformation of the polar headgroup of synthetic D-erythro-stearoylsphingomyelin (1), its L-threo-isomer (2) and phosphorothioyl analogues of 1 (3 and 4) has been studied in detail by high-resolution NMR spectroscopy. In both monomeric and aggregated states the phosphocholine function of 1 adopts the synclinal conformation (alpha 5 torsional angle), in… (More)
