NMR Spectroscopy of Lipid Bilayers

2010
Knowledge of lipid structure and dynamics in a membranous environment is of first importance for deciphering cellular function. Sterols and sphingolipids are key molecules in maintaining membrane integrity and are the building blocks of membrane domains, such as "rafts".

Phase transitions in supported lipid bilayers studied by AFM.

Soft Matter, 2014
We review the capabilities of Atomic Force Microscopy (AFM) in the study of phase transitions in Supported Lipid Bilayers (SLBs). AFM represents a powerful technique to cover the resolution range not available to fluorescence imaging techniques and where

Multiscale modeling of lipids and lipid bilayers

European Biophysics Journal, 2005
A multiscale modeling approach is applied for simulations of lipids and lipid assemblies on mesoscale. First, molecular dynamics simulation of initially disordered system of lipid molecules in water within all-atomic model was carried out. On the next stage, structural data obtained from the molecular dynamics (MD) simulation were used to build a ...

Monolayers and bilayers of lipids

Colloids and Surfaces, 1991
Abstract The spreading monolayers of ceramides alone and in mixtures with monooleoyl glycerol were studied at the air/water interface in the 15-30°C temperature range. The bidimensional phases were determined from the spreading isotherms of the pure components, whereas the interfacial miscibility of the compounds being studied was deduced from the ...

Binding of glucagon to lipid bilayers

Biochemistry and Cell Biology, 1990
At physiological pH and temperature, glucagon binds to liposomes composed of egg phosphatidylcholine and cholesterol (2:1 mol/mol) in a highly specific manner. The chemical reactivities of the functional groups were determined over the concentration range of 1.0 × 10−6 – 3.0 × 10−8 M by the method of competitive labelling with 1-fluoro-2,4 ...

Interaction of antihistamines with lipid bilayers

Biochemical Pharmacology, 1979
Abstract Interaction between a variety of antihistamines and lipid bilayers has been studied. The H 1 -antagonists all reduce the phase transition temperature of dipalmitoyl phosphatidylcholine, and these data have been used to calculate binding constants for the drug to lipid. The H 2 -antagonists cimetidine and metiamide have no effect on the lipid

Effect of functionalized gold nanoparticles on floating lipid bilayers.

Langmuir, 2013
The development of novel nano-engineered materials poses important questions regarding the impact of these new materials on living systems. Possible adverse effects must be assessed in order to prevent risks for health and the environment.

Photoelectrospectrometry of bilayer lipid membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1980
These different bilayer lipid membrane systems were studied under visible and ultraviolet illumination. The first system consisted of a bilayer lipid membrane formed with a mixture of phospholipids and cholesterol, to one side of which purple membrane fragments from Halobacterium halobium were added.
