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

TL;DR: The underlying approach to development of the CHARMM lipid force field, and the current ab initio and molecular dynamics methods for optimization of each term are reviewed in this article, where the importance of including long-range Lennard-Jones interactions and taking finite system size into account is stressed.

TL;DR: Cardiolipin with divalent cations can replace the role of phosphatidylethanolamine in the mutant strain, and that this role involves the preference of these lipids for organization in non-bilayer lipid structures.

Glycosphingolipid fatty acid arrangement in phospholipid bilayers: cholesterol effects
TL;DR: It would appear that the above factors impose a tendency for the "extra" portion of the 24-carbon chain to cross the bilayer midplane where it may interact with terminal portions of acyl chains in the opposing monolayer; however, steric constraints, and probably collision events associated with lateral diffusion, induce wide orientation fluctuations in the segment involved.

Molecular dynamics study of MscL interactions with a curved lipid bilayer
TL;DR: The results obtained suggest that through the geometry and composition of the bilayer the protein structure can be affected even on short timescales.

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.
