Cysteine hydrophilic or hydrophobic

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 ...
