WebCysteine has been considered as a "hydrophilic" amino acid because of its pK a and its ability to form (weak) hydrogen bonds. However, cysteines are found mostly in hydrophobic environments, either in S-S (disulphide) form or in free cysteine form. When free cysteines are found on the surface of proteins, they are often involved in catalytic ... WebIn 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 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).
