Impact of Cholesterol on Voids in Phospholipid Membranes
Emma Falck, Michael Patra, Mikko Karttunen +2
Free volume pockets or voids are important to many biological processes in cell membranes. Free volume fluctuations are a prerequisite for diffusion of lipids and other macromolecu…
Coarse-Grained Model for Phospholipid/Cholesterol Bilayer
Teemu Murtola, Emma Falck, Michael Patra +2
We construct a coarse-grained (CG) model for dipalmitoylphosphatidylcholine (DPPC)/cholesterol bilayers and apply it to large-scale simulation studies of lipid membranes. Our CG mo…
Lessons of Slicing Membranes: Interplay of Packing, Free Area, and Lateral Diffusion in Phospholipid/Cholesterol Bilayers
Emma Falck, Michael Patra, Mikko Karttunen +2
We employ 100 ns molecular dynamics simulations to study the influence of cholesterol on structural and dynamic properties of dipalmitoylphosphatidylcholine (DPPC) bilayers in the…
