Fig 2. Effect of cholesterol and CHIM on order parameters in DPPC bilayers.

Fig 2

Order of DPPC chains in DPPC (a) and DPPC/POPS (2:1) (b) mixtures containing CHOL, CHIM or a mixture of CHIM/CHOL, respectively, as a function of the cholesterol fraction within a total sterol concentration of 30 (a) and 20 (b) mol%. For comparison, the order of a pure DPPC bilayer and respective bilayers containing only CHIM-0 (the arbitrary charge-neutral CHIM-analog) is shown in the left and right panels, respectively. The color codes indicate the MD simulation temperatures, separating them in regimes of below (blues), above (reds), and near phase transition (black). The black dashed line is included to better distinguish between an ordered (S > 0.7) and disordered (S < 0.7) phase.
