Web[11] [12] Since cysteine forms disulfide bonds that must occur inside a globular structure, cysteine is ranked as the most hydrophobic. The first and third scales are derived from the physiochemical properties of the amino acid side chains. These scales result mainly from inspection of the amino acid structures. WebAug 29, 2006 · For example, a lysine side chain contains four methylenes, which may undergo hydrophobic interactions if the charged ε-NH3+group is salt-bridged or hydrogen-bonded. Folding initiation sites might therefore contain not only accepted “hydrophobic” amino acids, but also larger charged side chains.
