Fig. 8.

Helical net representations of synthetic amphipathic α-helical peptide standards. Residues comprising the non-polar face are circled, with lines between non-polar residues denoting i to i + 3 and i to i + 4 hydrophobic interactions between large hydrophobes along the helix. The shaded residues denote substitutions made in the “native” peptides: D1 in the +8 series D1–D4 and D14 in the +11 series D12–D14. Sequences of the peptides are shown in Table 2.
