Molecular Dynamics Simulations of Lipid Bilayers: Major Artifacts Due to Truncating Electrostatic Interactions
TL;DR: Pronounced maxima or minima in g(r) appear exactly at the cutoff distance indicating that the truncation gives rise to artificial ordering between the polar phosphatidyl and choline groups of the DPPC molecules, whereas in systems described using PME, such artificial ordering is not present.
Journal ArticleDOI
Under the Influence of Alcohol: The Effect of Ethanol and Methanol on Lipid Bilayers
Michael Patra,Emppu Salonen,Emma Terama,Ilpo Vattulainen,Roland Faller,Bryan W. Lee,Juha M. Holopainen,Mikko Karttunen +7 more
TL;DR: In this article, the effects of short-chain alcohols, methanol and ethanol, on two different fully hydrated lipid bilayer systems (POPC and DPPC) in the fluid phase at 323 K were investigated.
Journal ArticleDOI
Lessons of Slicing Membranes: Interplay of Packing, Free Area, and Lateral Diffusion in Phospholipid/Cholesterol Bilayers
TL;DR: It is found that cholesterol has a strong impact on the free area properties of the bilayer, highlighting the central role of free area in comprehending the structural and dynamic properties of membranes containing cholesterol.

Under the influence of alcohol: The effect of ethanol and methanol on lipid bilayers
Michael Patra,Emppu Salonen,Emma Terama,Roland Faller,Bryan W. Lee,Juha M. Holopainen,Mikko Karttunen +6 more
TL;DR: Hydrogen-bonding analysis reveals that a large fraction of ethanols is involved in hydrogen bonds with lipids, which is intimately coupled to the ordering of hydrocarbon chains: it is found that binding to an ethanol decreases the order of the chains.
Journal ArticleDOI
Systematic comparison of force fields for microscopic simulations of NaCl in aqueous solutions : diffusion, free energy of hydration, and structural properties
Michael Patra,Mikko Karttunen +1 more
TL;DR: It is shown that the uncertainties of the microscopic parameters of, in particular, sodium, and, to a lesser extent, chloride, translate into large differences in the computed radial‐distribution functions in biophysical simulations containing aqueous NaCl.
