We consider a model of lipids in which a head group, characterized by its volume, is attached to two flexible tails of equal length. The phase diagram of the anhydrous lipid is obtained within self-consistent field theory, and displays, as a function of lipid architecture, a progression of phases: body-centered cubic, hexagonal, gyroid, and lamellar. We then examine mixtures of an inverted hexagonal forming lipid and a lamellar forming lipid. As the volume fractions of the two lipids vary, we… 

Fluctuations in mixtures of lamellar- and nonlamellar-forming lipids

We consider the role of nonlamellar-forming lipids in biological membranes by examining fluctuations, within the random phase approximation, of a model mixture of two lipids, one of which forms

Molecular Theory Applied to Lipid Bilayers and Lipid–Protein Interactions

The physical properties and behavior of the lipid bilayer have been studied theoretically using a variety of models and techniques using atomistic molecular dynamics simulations, and these simulations have been able to treat patches of membrane up to a few tens of nanometers in lateral extent.

Self-assembly of copolymers and lipids

Block copolymers self assemble into a great array of stable, ordered, phases in which components of different blocks are separated. The basic reason for this is clear. The monomers comprising the

Field theoretic study of bilayer membrane fusion III: membranes with leaves of different composition.

Self-consistent field theory is employed, and while the fusion pathway exhibits two barriers in both the standard and alternative pathways, in both cases the magnitudes of these barriers are comparable to one another, and small, on the order of 13 k(B)T.

Alcohols reduce lateral membrane pressures: predictions from molecular theory.

The theory is used to study the effect of added alcohol on the lateral pressure profile across the membrane, and it is found that added alcohol reduces the surface tensions at both the head group/solvent and headgroup/tailgroup interfaces, as well as the lateral pressures in the headgroup and tailgroup regions.

Theory of tunable pH-sensitive vesicles of anionic and cationic lipids or anionic and neutral lipids.

Theory of tunable pH sensitive vesicles consisting of anionic and cationic lipids or anionic and neutral lipids

It is shown that both forms of vesicles have the desirable feature of exhibiting a regime in which the pH at instability is a rapidly varying function of the vesicle composition, and the mechanism in terms of the role of the counter ions is explicate.

ec 2 00 2 Mechanism of Model Membrane Fusion Determined from Monte Carlo Simulation

We have carried out extensive Monte Carlo simulations of the fusion of tense apposed bilayers formed by amphiphilic molecules within the framework of a coarse grained lattice model. The fusion



Calculation of the phase behavior of lipids

The self-assembly of monoacyl lipids in solution is studied employing a model in which the lipid's hydrocarbon tail is described within the rotational isomeric state framework and is attached to a

Phase Behavior of Block Copolymer/Homopolymer Blends

We examine weakly segregated blends of AB diblock copolymer and A homopolymer with similar degrees of polymerization. The relative stability of numerous phases is examined and phase diagrams are

Origins of Complex Self-Assembly in Block Copolymers

Amphiphilic molecules are renowned for their ability to partition chemically immiscible components into nanoscale domains. Often these domains exhibit intriguing complex periodic geometries with

Wild-type Escherichia coli Cells Regulate the Membrane Lipid Composition in a Window between Gel and Non-lamellar Structures (*)

It is concluded that the regulation of the acyl chain composition in wild-type cells of E. coli is necessary for the organism to be able to grow in a “window” between a lamellar gel phase and reversed non-lamellar phases.

Ordered and curved meso-structures in membranes and amphiphilic films

Curvature-induced instabilities in membranes and amphiphilic films are investigated by introducing a general coupling between a shape variable (such as curvature) and «internal» degrees of freedom

Influence of cholesterol on the structural preferences of dioleoylphosphatidylethanolamine-dioleoylphosphatidylcholine systems: a phosphorus-31 and deuterium nuclear magnetic resonance study.

2H NMR studies of appropriately labeled versions of these systems indicate that cholesterol does not produce such effects by associating preferentially with either DOPE or DOPC, and in situations where bilayer, hexagonal, or "isotropic" phases coexist in the same sample, the phospholipids exhibit apparently ideal mixing behavior.
