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.

The morphology of lipid membranes
Current Opinion in Structural Biology, 1995Current research into the morphology of lipid membranes focuses on three areas: first, the transformations and fluctuations of the shape of freely suspended vesicles; second, the morphology of membranes that experience mutual interactions or external forces arising, for example, from a macroscopic surface or from optical tweezers; and third, the ...

On the Lipid Composition of Membranes
Protoplasma, 1967The lipid content of membrane preparations isolated from different origins has been demonstrated to vary from 30% to 75% on a dry weight basis. Depending on the procedure utilized for the preparation of red cell ghosts, this membrane was found to contain either 30% or 50% lipids, cholesterol and phospholipids, which together account for over 80% of the

Biosynthesis of Membrane Lipids
EcoSal Plus, 2008The 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.

Lipid polymorphism and the roles of lipids in membranes
Chemistry and Physics of Lipids, 1986The reasons for lipid diversity in membranes are not understood. Here we review evidence supporting the proposal that factors related to the polymorphic capabilities of lipids provide a rationale for lipid diversity. In particular, the ability of lipids to adopt different polymorphic phases appears to be related to a generalized shape property, where ...

The lipid matrix of biological membranes is composed of a complex mixture of polar lipids. It has been estimated that more than 600 distinct molecular species of lipid are constituents of biological membranes. This rather remarkable feature raises the questions of why such complexity is required when barrier properties and many protein functions can be

The interaction of lipid modified pseudopeptides with lipid membranes
Organic & Biomolecular Chemistry, 2011We have studied the structure of two lipopeptides based on the simple dipeptide building block L-Phe-D-Oxd. These peptides have been reported previously to form fiber-like materials. The lipopeptides synthesized here had the structures C(n)(2)H((2n+1))CO-L-Phe-D-Oxd-OBn or C(n)(2)H((2n+1))CO-D-Phe-L-Oxd-OBn with n = 5 or 11.

Lipid Membranes for Membrane Proteins
2014The 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,

Globin Interactions with Lipids and Membranes
2008Many bacterial globins have been demonstrated to interact with membrane lipids, and several hypotheses in support of a functional role for membrane localization have been set forth. Bacterial globins have been suggested to facilitate oxygen diffusion to terminal oxidases, to protect oxidases from nitric oxide or eventually to preserve the integrity of ...
