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 nine amino acids that have hydrophobic side chains are glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp).

The hydrophobicity index is a measure of the relative hydrophobicity, or how soluble an amino acid is in water. Hydrophobic Amino Acids: What are hydrophobic and polar groups Amino acids are grouped according to what their side chains are like.
