(a) Experimental and simulated water-permeability values for DPPC as a function of temperature. Simulation values include the average of two Slipids simulations at 293 K (NMRlipids IDs 247 and 46) (Javanainen, 2017

), an Slipids simulation at 300 K (ID 542) (Javanainen et al., 2017

), a CHARMM36 simulation at 305 K (ID 406) (Javanainen et al., 2019

) and an Slipids simulation at 310 K (ID 567) (Javanainen et al., 2017

). (b) Activation energy for water permeability in DPPC, extracted from experimental (red) and simulation (black) data.
