TLDR
Proton and carbon-13 nmr spectra of unsonicated lipid bilayers and biological membranes are generally dominated by strong proton-proton and proton–carbon dipolar interactions and are rather difficult to analyse.Abstract:
Proton and carbon-13 nmr spectra of unsonicated lipid bilayers and biological membranes are generally dominated by strong proton–proton and proton–carbon dipolar interactions. As a result the spectra contain a large number of overlapping resonances and are rather difficult to analyse. Nevertheless, important information on the structure and dynamic behaviour of lipid systems has been provided by these techniques (Wennerstrom & Lindblom, 1977).read more

Physical properties of the fluid lipid-bilayer component of cell membranes: a perspective.
TL;DR: The motivation for this review arises from the conviction that, as a result of the mass of experimental data and observations collected in recent years, the study of the physical properties of membranes is now entering a new stage of development.

TL;DR: DHA's interaction with other membrane lipids, particularly cholesterol, may play a prominent role in modulating the local structure and function of cell membranes.

Magnetic resonance of perdeuterated potassium laurate in oriented soap-water multilayers
TL;DR: The deuteron resonance of five of the eleven methylene and methyl groups of the paraffinic chains is distinctly resolved in this article, and the orientation of the monocrystalline lamellar mesophare is varied with respect to the external magnetic field.

Lipid mobility in Acholeplasma membranes using deuteron magnetic resonance
TL;DR: Deuteron magnetic resonance spectroscopy of the deuterated lipids in intact membranes indicated that the lipids were in a state of mobility rather similar to that of the gel state of dimyristoyl lecithin, consistent with results obtained by differential scanning calorimetry and X-ray diffraction.
