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

Physical properties of the fluid lipid-bilayer component of cell membranes: a perspective.
TL;DR: The motivation for this review arises from the conviction that, as a result of the mass of experimental data and observations collected in recent years, the study of the physical properties of membranes is now entering a new stage of development.

TL;DR: DHA's interaction with other membrane lipids, particularly cholesterol, may play a prominent role in modulating the local structure and function of cell membranes.

Nature of the Thermal pretransition of synthetic phospholipids: dimyristolyl- and dipalmitoyllecithin.
TL;DR: The hydrated synthetic lecithins, dimyristoyl and dipalmitoyllecithin, undergo two thermal transitions, a broad low enthalpy "pretransition" prior to the sharp first-order "chain-melting" transition and a structural transformation from a one-dimensional lamellar to a two-dimensional monoclinic lattice consisting of lipid lamellae distorted by a periodic ripple.

TL;DR: The field of electric quadrupole interactions in nuclear magnetic resonance can be divided roughly into two areas according to the relative magnitude of the nuclear quadrupoles interactions as discussed by the authors, which can be classified into two categories according to their relative importance.

On the quantitative interpretation of biomembrane structure by Raman spectroscopy.
TL;DR: The Raman technique is extended through an examination of the origins of the structure-sensitive features of phospholipid spectra and the development of quantitative order-parameters to find that the vesicles of dipalmitoyl phosphotidylcholine are substantially less ordered than the dispersions in terms of both longitudinal and lateral order.
