Figure 4.

Panel A: Correlation plot of the hydrophobicity/hydrophilicity coefficients at the C-terminus with a Cα-carboxyl group versus internal side-chain coefficients (data taken from Peptide 1 and Peptide 5, Table 3). The peptide sequences are shown in Table 1. The hydrophobic amino acid side-chains are denoted by the single letter code. Y = 0.985 x − 0.497, correlation coefficient R = 0.984. Panel B: The difference in coefficients between Peptide 1 and Peptide 5 are plotted as a bar graph (data taken from Table 3).
