(a) Most representative equilibrium structures of peptides #6, #11 and #12, obtained by MD simulations. (b) Ramachandran plots showing the values of the psi (Ψ) and phi (Φ) angles assumed by each residue, as indicated. (c) Electrostatic potential of the peptides, shown as surfaces; red, blue and white colors are used for negative (−3 kT/e), positive (+7 kT/e), and zero values, respectively.
