  • Title: A nuclear magnetic resonance study of sphingomyelin in bilayer systems.
    Author: Schmidt CF, Barenholz Y, Thompson TE.
    Journal: Biochemistry; 1977 Jun 14; 16(12):2649-56. PubMed ID: 889781.
    Abstract:
    The physical properties of small single-walled vesicles composed of the zwitterionic phospholipid sphingomyelin have been studied using 1H and 31P nuclear magnetic resonance spectroscopy. The temperature variation of proton line widths and spin-lattice relaxation times and the chemical shift behavior for sphingomyelin vesicles are compared with results previously determined for phosphatidylcholine vesicles. Differences between the two systems are interpreted as indications of the presence of both inter- and intramolecular hydrogen bonding in sphingomyelin bilayers.
