Our recent studies have indicated that aqueous dispersions of galactosylceramides (GalCers) containing nervonoyl [24:1Δ15(CiS)] acyl chains, which constitute the major unsaturated acyl moieties in bovine brain GalCer, form tubular bilayers. In an effort to define the structural parameters that modulate tubule formation, we synthesized a series.of GalCers having successively shorter cis monounsaturated acyl chains than the tubule-forming 24:1 GalCer and investigated the resulting microstructural self-assemblies by freeze fracture and deep etch electron microscopy.GalCers having W-linked erucic [22:1Δ13(CiS)], eicosenoic [20:Δ11(CiS)], or oleic [18:Δ9(CiS)] acyl chains were synthesized and purified as previously reported for 24:1 GalCer. Dispersions were prepared by hydrating dry lipid at >90°C with phosphate buffer (pH 6.6) followed by vigorous vortexing and three freeze-thaw cycles. Samples were cryo-fixed from room temperature (22°C) by plunging into liquid propane cooled by liquid nitrogen, were fractured in a Balzers 300 freeze fracture apparatus at -120°C, and were etched for 6 min. at -100°C.
