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

Resistance of Human Erythrocyte Membranes to Triton X-100
Cleyton C. Domingues,Annarita Ciana,Armando Buttafava,Cesare Balduini,Eneida de Paula,Giampaolo Minetti +5 more
TL;DR: In this article, the authors compared DRMs from human erythrocytes prepared with two detergents: Triton X-100 and C12E8, and found that the DRMs obtained presented a choesterol/protein mass ratio three times higher than in the whole membrane.

Naturally Occurring Amphiphiles: Aspects of Their Phase Behavior
TL;DR: In this article, a discussion of naturally occurring amphiphiles will be confined to the class of phospholipids, which are major constituents of biological membranes and serum lipoproteins.

Rheology of the lecithin-water system in its lamellar phase
D. Bourgoin,W. Shankland +1 more
TL;DR: In this paper, the authors examined the rheological properties of lecithin in its lamellar phase by means of a Weissenberg Rheogoniometer and showed that the dispersions show a plastic flow behavior with a stress varying only a little as the rate of shear decreases to zero.

Partition coefficients of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) in erythrocyte lipids in multiple sclerosis
TL;DR: A small, nonelectrolyte spin label, TEMPO, was chosen; its partition coefficient was determined in extracted erythrocyte lipids from MS patients and normal controls; no differences were observed.

Swelling of Water/Nonionic Surfactant Lamellar Liquid Crystals: A Model
TL;DR: In this article, a model is presented to provide quantitative measures to estimate the trends of the change in the penetration of the added component into the polar part of the amphiphile layer in lamellar liquid crystals of water and ethoxylated surfactants with added water (or polar solvents).

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.
