WebWhat type of bond is a disulfide bond? covalent bond A disulfide bond is a covalent bond between two sulfur atoms (–S–S–) formed by the coupling of two thiol (–SH) groups. Cysteine, one of 20 protein amino acids, has a –SH group in its side chain, and can easily be dimereized to cystine in aqueous solution by forming a disulfide bond. WebHowever, like the hydrogen bond, salt bonds are not particularly strong. Ph can break these bonds easily by solid alkaline or acidity. Unlike the physical hydrogen and salt bonds, a disulfide bond is a strong, chemical side bond.
