Lipid fractions as a function of compressional strain (curvature) for the IM−1 system. The lipid fraction of PC (A), PE (B) and CL−1 (C) are shown. The legend in B applies to all panels. The curvature regions were defined as follows: negative: C < −0.05; neutral: 0.05 ≤ C ≤ 0.05; positive: C > 0.05, where curvature units are nm−1.
