Cysteine (abbreviated to Cys or C) is an amino acid with the side chain -CH2SH. Cysteine, like methionine, contains sulphur. It is a non-polar amino acid that contains a very reactive thiol or sulfhydryl group (-SH). The presence of this group allows cysteine to form strong disulphide bridges when paired with another cysteine. Cysteine therfore plays an important structural role in proteins [1].
