Density of the overall hydrophobicity on the molecular surface of hemoglobin subset, at small (top) and large (bottom) probe radius vs. the hydrophobicity of the residue 37.

<p>The hydrophobicities of the residue 37 are, from left to right, Gly, Ala, Glu, Tyr and Trp <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0114042#pone.0114042-Wimley1" target="_blank">[38]</a>.
