Structure of lipid bilayers [PDF]
The quantitative experimental uncertainty in the structure of fully hydrated, biologically relevant, fluid (L(alpha)) phase lipid bilayers has been too large to provide a firm base for applications or for comparison with simulations. Many structural methods are reviewed including modern liquid crystallography of lipid bilayers that deals with the fully

Fluctuations, inherent in flexible and biologically relevant lipid bilayers, make quantitative structure determination challenging. Shortcomings in older methods of structure determination have been realized and new methodologies have been introduced that take fluctuations into account.

Correlated diffusion in lipid bilayers [PDF]
SignificanceDynamic processes on membrane surfaces are essential for biological function. Traditionally, quantitative measurements of lipid/protein motion have been interpreted in the framework of membrane hydrodynamics. However, some recent single-molecule tracking studies have proven difficult to interpret via hydrodynamic arguments.

Glycophorin in Lipid Bilayers [PDF]
Glycophorin, the major glycoprotein of human erythrocytes, has been isolated and reincorporated into lipid vesicles. Freeze-fracture electron microscopy shows the reincorporated glycophorin to occur as small particles in vesicle fracture faces while the etch faces are smooth.

Volumetric stability of lipid bilayers [PDF]
In agreement with recent reports, a commercial densimeter has yielded a gradual decrease in lipid molecular volume of DPPC multilamellar vesicle dispersions in the gel phase upon repeated thermal cycling between 10 °C and 50 °C. The considerable size of this decrease would have significant implications for the physical chemistry of biomembranes.

Alcohol Interactions with Lipid Bilayers [PDF]
We investigate the structural changes to lipid membrane that ensue from the addition of aliphatic alcohols with various alkyl tail lengths. Small angle neutron diffraction from flat lipid bilayers that are hydrated through water vapor has been employed to eliminate possible artefacts of the membrane curvature and the alcohol’s membrane-water ...

Composition Fluctuations in Lipid Bilayers [PDF]
AbstractLipid bilayers constitute the basis of biological membranes. Understanding lipid mixing and phase behavior can provide important insights into membrane lateral organization (the “raft” hypothesis). Here we investigate model lipid bilayers below and above their miscibility transition temperatures.

Lipid Bilayers of Ester-Modified Lipids [PDF]
Lipid membranes and bilayers essentially function as barriers for cells to control the transport of substances. Since phospholipid membranes consist of a hydrophilic surface and a hydrophobic inside, the center of a phospholipid bilayer is known to contain almost no water and to prevent the transport of water-dissolving substances, such as ions.
