Composition Fluctuations in Lipid Bilayers [PDF]
Biophysical Journal, 2016 AbstractLipid bilayers constitute the basis of biological membranes. Understanding lipid mixing and phase behavior can provide important insights into membrane lateral organization (the “raft” hypothesis). Here we investigate model lipid bilayers below and above their miscibility transition temperatures.

Interaction of the Antimicrobial Peptide Aurein 1.2 and Charged Lipid Bilayer
Scientific Reports, 2017 Aurein 1.2 is a potent antimicrobial peptide secreted by frog Litoria aurea. As a short membrane-active peptide with only 13 amino acids in sequence, it has been found to be residing on the surface of lipid bilayer and permeabilizing bacterial membranes ...

Cholesterol Perturbs Lipid Bilayers Nonuniversally [PDF]
Physical Review Letters, 2008 Cholesterol is well known to modulate the physical properties of biomembranes. Using modern x-ray scattering methods, we have studied the effects of cholesterol on the bending modulus KC, the thickness DHH, and the orientational order parameter Sxray of lipid bilayers.

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.
