Selenocysteine is an amino acid that has the same side-chain as a normal cysteine molecule, but with the sulphur atom replaced with a selenium atom. This gives it the side chain -CH(NH2)-CH2-SeH. Although much more uncommon than the other 20 amino acids used to make most proteins, selenocysteine appears in a few proteins that carry out redox reactions[1].
