Difference in molecular mechanisms governing changes in membrane properties of phospholipid bilayers induced by addition of nonionic and zwitterionic surfactants [PDF]

, 2018
We investigated how nonionic surfactants (1-dodecanol, dodecyl methyl ester, and dodecanoic acid) and zwitterionic surfactants (N,N-dimethyldodecylamine N-oxide, and 1-lauroyl-2-hydroxy-sn-glycero-3-phosphatidylcholine) change the physicochemical ...

Controlled delivery of membrane proteins to artificial lipid bilayers by nystatin-ergosterol modulated vesicle fusion

, 2006
The study of ion channels and other membrane proteins and their potential use as biosensors and drug screening targets require their reconstitution in an artificial membrane.

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.

Binding Orientations and Lipid Interactions of Human Amylin at Zwitterionic and Anionic Lipid Bilayers

Journal of Diabetes Research, 2016
Increasing evidence suggests that the interaction of human islet amyloid polypeptide (hIAPP) with lipids may facilitate hIAPP aggregation and cause the death of pancreatic islet β-cells.
