Amino acid residue pka of ionizing side chaina. Percent buried (%) residuesd (%) van der waals. 4 (3) athe pka values in most cases are at 25 c. 1985. ) eaverage volume (vr) of buried residues, calculated from the surface area of the side chain (richards 1977; baumann et al. 1989). fdata from darby and creighton (1993). gtotal accessible surface area (asa) of amino acid side chain for residue x in a gly-x-gly tripeptide with the main chain in an extended conformation (miller et al. The lower rankings represent the most hydrophobic amino acids, and higher values represent the most hydrophilic amino acids. For comparative purposes, the hydrophobicity scale of radzicka and wolfenden is shown in parentheses.
