Evidence for the Formation of Symmetric and Asymmetric DLPC-DAPC Lipid Bilayer Domains
Cellular Physiology and Biochemistry, 2013 Background/Aims: We investigated if mixtures of the phosphatidylcholine (PC) lipids 1,2-dilauroyl-sn-glycero-3-phosphocholine (C12:0 PC; DLPC) and 1,2-diarachidoyl-sn-glycero-3-phosphocholine (C20:0 PC; DAPC), which differ by eight methylene groups in ...

Cholesterol's location in lipid bilayers [PDF]
Chemistry and Physics of Lipids, 2016 It is well known that cholesterol modifies the physical properties of lipid bilayers. For example, the much studied liquid-ordered Lo phase contains rapidly diffusing lipids with their acyl chains in the all trans configuration, similar to gel phase bilayers. Moreover, the Lo phase is commonly associated with cholesterol-enriched lipid rafts, which are

Lipid/water interface of galactolipid bilayers in different lyotropic liquid-crystalline phases
Frontiers in Molecular Biosciences, 2022 In this study, carried out using computational methods, the organisation of the lipid/water interface of bilayers composed of galactolipids with both α-linolenoyl acyl chains is analysed and compared in three different lyotropic liquid-crystalline phases.

Electrostatics of lipid bilayer bending
Biophysical Journal, 1997 The electrostatic contribution to spontaneous membrane curvature is calculated within Poisson-Boltzmann theory under a variety of assumptions and emphasizing parameters in the physiological range. Asymmetric surface charges, either fixed with respect to bilayer midplane area, or with respect to the lipid-water area both induce curvature but of opposite

Functional tethered lipid bilayers
Reviews in Molecular Biotechnology, 2000 Our strategy to provide the structural basis for the build-up of functional tethered membranes focuses on three approaches: the first one is based on the pre-organization of a monomolecular layer of a lipopolymer at the water/air interface which is then transferred to a solid support.

Correlated diffusion in lipid bilayers [PDF]
Proceedings of the National Academy of Sciences, 2021 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.
