Lipid-lipid and lipid-protein interactions in membranes

Pharmacology Biochemistry and Behavior, 1980
Over the past decade spectroscopic methods (fluorescence, ESR, and NMR) have been used to provide new information about the molecular dynamics of lipid-lipid and lipid-protein interactions in membranes. The various methods of characterizing isotropic and anisotropic motion are described.

Hydrogel-Encapsulated Lipid Membranes

Journal of the American Chemical Society, 2005
We have encapsulated free-standing planar lipid membranes in a polymer hydrogel via in situ photopolymerization. These encapsulated membranes were measured to last at least 5 days and provided a stable environment for single-molecule measurements of incorporated alpha-hemolysin channel proteins.

Polyelectrolyte-supported lipid membranes

Bioelectrochemistry, 2002
In this work, we report the influence of the electrostatic interaction between lipid bilayer membranes and their solid polyelectrolyte multilayer support on the properties of the membrane. All involved sample preparation steps were carried out as convenient adsorption procedures from aqueous solutions.

Lipid Membranes for Membrane Proteins

2014
The molecular dynamics (MD) simulation of membrane proteins requires the setup of an accurate representation of lipid bilayers. This chapter describes the setup of a lipid bilayer system from scratch using generally available tools, starting with a definition of the lipid molecule POPE, generation of a lipid bilayer, energy minimization, MD simulation,

Neuronal membrane lipid asymmetry

Life Sciences, 1979
Abstract The outer surface of intact synaptosomes was covalently labelled with trinitrobenzenesulfonic acid prior to isolation of the synaptic plasma membrane. Analysis of the membrane lipid demonstrated an asymmetric distribution of phospholipids across the synaptosomal plasma membrane.

Lipids in amniotic membranes

American Journal of Obstetrics and Gynecology, 1965
Abstract 1. 1. Total lipids, phospholipids, esterified fatty acids (EFA), and cholesterol were studied in 167 amniotic membranes. These membranes were taken from 60 women of European origin, 63 women of Oriental origin, and 44 women of Yemenite origin. Venous blood was also studied for total lipids in these three groups of women. 2. 2.

Spherical lipid bilayer membranes

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1967
Abstract 1. 1. The formation of a new model membrane system is described. In its final configuration this system consists of four phases: a spherical bilayer membrane several mm in diameter, a bulk lipid phase which takes the form of a cap or lens covering less than 10% of the spherical surface, and two aqueous phases, one on each side of the ...

Biosynthesis of Membrane Lipids

EcoSal Plus, 2008
The pathways in Escherichia coli and (largely by analogy) S. enterica remain the paradigm of bacterial lipid synthetic pathways, although recently considerable diversity among bacteria in the specific areas of lipid synthesis has been demonstrated.

Ethanol and Membrane Lipids

Alcoholism: Clinical and Experimental Research, 1985
Although ethanol is known to exert its primary mode of action on the central nervous system, the exact molecular interaction underlying the behavioral and physiological manifestations of alcohol intoxication has not been elucidated. Chronic ethanol administration results in changes in organ functions.
