Figure 3

The concentration-dependent tilt angle distribution of the oxidized sn-2 chains of PazePC (a) and PoxnoPC (b). The numbers in the legend refer to the number of OXPLs present in each simulation. The tilt angle was defined as the angle between the bilayer normal and the vector from the last to the first carbon atom of the oxidized sn-2 acyl chain. A tilt angle of 0° indicates an sn-2 chain in the hydrocarbon interior of the bilayer and antiparallel to the bilayer normal. A tilt angle of 180° indicates an sn-2 chain pointing into the aqueous phase and parallel to the bilayer normal. The distribution for a POPC oleoyl chain (thick gray line) is from the pure POPC simulation.
