Figure 4

Peptide order parameter. (a) The probability distribution of the angle between the backbone carbonyl bond, C=O, in the β-strands and the normal to the lipid bilayer surface for the antiparallel (A1 (solid line) & A2 (dotted line)) and parallel (P1 (solid line) & P2 (dotted line)) β-sheets. (b) The probability distribution of the peptide order parameter, SC=O, for the antiparallel (A1 (solid line) & A2 (dotted line)) and parallel (P1 (solid line) & P2 (dotted line)) β-sheets. The numbers in the bracket denote the initial values of SC=O in the starting points.
