Figure 2.

Computer snapshots of equilibrium (low-energy) conformer of the AMPs as anionic species from MC simulations. Atoms are color-coded: C (white), H (green), O (red). All the structures depicted in the figure are oriented such that their dipole moment is aimed in the vertical direction with the negative pole pointing upward. Inspection of each structure reveals that there is a distinct separation between the hydrophilic groups (carboxyl and PEG) and the hydrophobic arms.
