"WebPolar (uncharged) Cysteine is one of two sulfur-containing amino acids; the other is methionine. Cysteine differs from serine in a single atom-- the sulfur of the thiol replaces the oxygen of the alcohol. The amino acids are, however, much more different in their physical and chemical properties than their similarity might suggest. " - Cysteine biology
