Hydrogen bonding peptide-based amphiphiles

Figure 6.3 Self-assembled nanostructures based on P-sheet (a) peptides packing into sheets and fibers based on hydrophobic interactions on one face of the molecule, and complementary ionic interaction on the other (b) peptides with alternating hydrophilic and hydrophobic residues assemble into P-sheet structures (left) that form twisted ribbons (right) and bundle into larger fibers and (c) self-assembly based on amphiphilic triblock peptides, where the central hydrophobic block forces self-assembly via hydrophobic interactions between molecules and hydrogen bonding along the fiber axis.
