On the ordering of N-alkane and N-alcohol solutes in phospholipid bilayer model membrane systems
2 H-NMR measurements of the ordering of several n-alkane and one n-alcohol solutes in lipid bilayers formed from dimyristoyl lecithin (DML) are reported. The results are consistent with orientation of the solutes between the lipid chains, the n-alkanes having a preference for the bilayer interior, w...

Summary: | 2 H-NMR measurements of the ordering of several n-alkane and one n-alcohol solutes in lipid bilayers formed from dimyristoyl lecithin (DML) are reported. The results are consistent with orientation of the solutes between the lipid chains, the n-alkanes having a preference for the bilayer interior, while the n-octanol is anchored at the bilayer surface. Solubility of the short chain n-alkanes, n-hexane and n-octane as an ordered component in the L α phase is more limited than that of n-dodecane. The NMR data are supported by low angle X-ray diffraction results which confirm that n-octanol has a more dramatic influence on bilayer area than the n-alkanes. |
