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

Structural and motional properties of vesicles as revealed by nuclear magnetic resonance
TL;DR: Questions regarding both static and dynamic aspects of membrane structure can be probed via an almost limitless number of pulse sequences, thereby providing a wealth of information not easily obtained from other techniques.

Lamellar structures formed by stratum corneum lipids in vitro: a deuterium nuclear magnetic resonance (NMR) study.
TL;DR: Hydrated lipid mixtures consisting of stratum corneum ceramides, cholesterol, specifically deuterated palmitic acid, and cholesteryl sulfate were investigated by solid-state 2H NMR spectroscopy at different temperatures.

Statistical thermodynamics of alkyl chain conformations in lipid bilayers
TL;DR: In this article, the authors examined the conformations and packing of the chains in bulk n-alkane in low temperature crystals, the intermediate α-crystal state and in the liquid state.

The membrane-induced structure of melittin is correlated with the fluidity of the lipids.
TL;DR: The study shows that bicelles can be used to investigate lipid dynamics by spin relaxation, and in particular of peptide-induced changes in membrane fluidity.

Molecular order and dynamics of diphytanylglycerol phospholipids: a 2H and 31P-NMR study☆
TL;DR: 2H NMR and 31P-NMR data indicated that both the hydrocarbon-glycerol ether linkage and the presence of the branch methyl groups have a marked effect on the physical properties (both conformation and dynamics) of the hydro carbon chains.

Principles of magnetic resonance
TL;DR: In this article, the effect of changing the precession frequency of the magnetic field has been studied using NMR to study rate properties. But the effect is limited to the case of double and double resonance.
