Disulphide bond

A disulphide bond (or SS-bond) is a strong covalent bond which, by way of oxidation, couples the thiol groups of two cysteine amino acids in a peptide sequence (or protein). In the case of toxins, these disulphide bonds allow peptides to maintain the three-dimensional conformation needed to bond with their target receptors.
