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

Distribution of Neutral Prilocaine in a Phospholipid Bilayer: Insights From Molecular Dynamics Simulations
TL;DR: In this article, a 20ns constant pressure molecular dynamics simulation of prilocaine (PLC), an amineamide local anesthetic, in a hydrated liquid crystal bilayer of 1-palmitoyl-2-oleoylsn-glycero-3-phosphatidylcholine is presented.

TL;DR: This study showed that V. splendidus can be labelled using deuterated palmitic acid, and demonstrated the importance of surfactant choice in the labelling protocol, and assessed the impact of lipid deuteration on the general fitness of the bacteria, as well as the saturated-to-unsaturated fatty acid chains ratio and its impact on the membrane properties.

Link between Fluorescent Probe Partitioning and Molecular Order of Liquid Ordered-Liquid Disordered Membranes.
TL;DR: 2H NMR measurements suggest that the strength of fluorescent probe partitioning between liquid ordered and liquid disordered phases correlates with the degree of perturbation to membrane phase behavior.

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.
