Lyu Lab. The scales were extrapolated to residues which are more hydrophilic than glycine. Putnam, The Scripps Research Institute, U.S.A.) - calculates mass, pI, charge at a given pH, counts amino acid residues etc. The values in the table below are normalized so that the most hydrophobic residue is given a value of 100 relative to glycine, which is considered neutral (0 value). In a protein, hydrophobic amino acids are likely to be found in the interior, whereas hydrophilic amino acids are likely to be in contact with the aqueous environment.

The hydrophobicity index is a measure of the relative hydrophobicity, or how soluble an amino acid is in water.
