Lipids out of equilibrium: Energetics of desorption and pore mediated flip-flop

DP Tieleman, SJ Marrink - Journal of the American Chemical …, 2006 - ACS Publications
The potential of mean force (PMF) of a phospholipid in a bilayer is a key thermodynamic
property that describes the energetic cost of localized lipid defects. We have calculated the …

Thermodynamics of flip-flop and desorption for a systematic series of phosphatidylcholine lipids
