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

Biphenyl bicelle disks align perpendicular to magnetic fields on large temperature scales : A study combining synthesis, solid-state NMR, TEM, and SAXS
TL;DR: The two types of bicelles present orienting properties up to 95% dilution but with the peculiarity that water trapped in biphenyl bicella exhibits ordering properties twice as large as those observed in the saturated-chains analog, which offers very interesting properties for structural studies on hydrophilic or hydrophobic embedded biomolecules.

Lanosterol and Cholesterol-Induced Variations in Bilayer Elasticity Probed by 2H NMR Relaxation
TL;DR: By correlating the NMR relaxation behavior with the order parameters, the results are explained by a progressive reduction of the bilayer elasticity, which parallels the biosynthetic pathway from lanosterol to cholesterol.

Anthracenoyl crown ethers and cryptands as fluorescent probes for solid-phase transitions of phosphatidylcholines: syntheses and phospholipid membrane studies
TL;DR: Due to its large change of fluorescence intensity, the anthracenophane cryptand is a very sensitive probe for the detection of the pretransition of symmetrically substituted and of the subtransition of asymmetrally substituted phosphatidylcholines.

Synthesis of isotopically labeled saturated fatty acids.
TL;DR: An approach to the synthesis of isotopically labeled saturated fatty acids is outlined which is based on the copper-catalyzed coupling of an omega-bromo acid with an isotopical labeled Grignard reagent.

TL;DR: It is concluded that the foamability is related to the phase behavior in aqueous solution, whereas for other alkyl chains, poor or no foam is formed.

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.
