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

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.

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.

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.

Lipid-lipid and lipid-protein interactions in membranes
Pharmacology Biochemistry and Behavior, 1980Over 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.

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

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 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 ...

The most important components that make up cell membranes are various types of lipids. By cataloging lipid structures (referred to as lipidomics), eukaryotic cells have been found to invest substantial resources in generating various types of lipids. Cells use about 5 % of their genes to encode for the synthesis of these lipids.

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,
