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

Études biophysiques d'un peptide amyloïde et de ses interactions avec des membranes modèles
TL;DR: The main objective of this thesis was to characterize the structure of the AP (25-35) peptide as a function of many physico-chemical conditions, in the absence and in the presence of membranes, and to explore the protective role of cholesterol in these interactions.

A 31P- and 2H-NMR study on lecithins in liquid crystalline polyoxyethylene detergents
TL;DR: It is shown by nuclear magnetic resonance (NMR) that the phospholipids adopt the hexagonal liquid crystalline structure of the detergent host lattice and becomes immobilized after a few weeks of storage below the transition temperature as judged from 31P-NMR.

14N NMR spectroscopy of NH4+ as a probe of ion‐exchange membranes
TL;DR: In this article, it was shown that spin-lattice relaxation times in all three membranes at 300 K are about 20 times shorter than in aqueous solution, consistent with strongly bound NH4+ ions.

TL;DR: The average conformation of the methyl-branched chains of archaeal lipid, phosphatidyl glycerophosphate methyl ester (PGP-Me), was examined in hydrated bilayer membrane base on the solid state NMR of enantioselectively 2H-labeled compounds that were totally synthesized for the first time in this study.

NMR and X-Ray Investigation of the Phase Behavior of Phosphatidylethanolamines
TL;DR: The second moments of the proton magnetic resonance lines of DPPE and DMPE, below the main phase transition, vary within a similar range as those of the corresponding phosphatidylcholines as mentioned in this paper.

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.
