Cysteine (abbreviated as Cys or C) is an α-amino acid with the chemical formula HO2CCH(NH2)CH2SH.
Its codons are UGU and UGC. With a thiol side chain, cysteine is classified as a hydrophobic amino acid. Because of the high reactivity of this thiol, cysteine is an important structural and functional component of many proteins and enzymes. Cysteine is named after cystine, its oxidized dimer.
