Molecular packing in sphingomyelin bilayers and sphingomyelin/phospholid mixtures.
The molecular packing properties of sphingomyelin (SM) from egg yolk were studied. The influence of the spontaneous curvature of SM on the phase behaviour of SM/dodecane/water systems was investigated. A comparison was made to a previous study by Lindblom et al. (Liq. Cryst. 3 (1988) 783), of the phase behaviour of dipalmitoylphosphatidylcholine (DPPC)/dodecane/water systems, where a reversed hexagonal liquid crystalline was shown to form at high water contents (60-80%, w/w). In contrast, SM/dodecane/water systems mainly maintained a lamellar liquid crystalline phase at all compositions and temperatures >35 degrees C. This suggests that the spontaneous curvature of SM is larger than for DPPC. To further examine the packing properties of SM and DPPC, the phase behaviour of SM/dioleoylphosphatidylethanolamine (DOPE)/water and DPPC/DOPE/water systems were investigated. Aqueous dispersions of DOPE normally form a reversed hexagonal liquid crystalline phase, while an isotropic phase was formed at small additions (20 mol.%) of SM or DPPC and a lamellar liquid crystalline phase was maintained at higher fractions (>35 mol.%) of SM or DPPC.
