The disulfide bridge they create is one of the most quietly important covalent bonds in biochemistry, the bond that lets folded proteins keep their shape across the conditions of the cell. The Chemistry of Cystine Disulfide bonds form when the thiol groups of two cysteine residues are oxidised, releasing two
