It is basically a covalent type bond. Disulfide bond is formed by the oxidation of sulfyhydryl or thiol group (S-H group), present only in Cysteine amino acid (non essential amino acid). It is also known as S-S bond . Disulfide bond is denoted by R-S-S-R1.

WebA disulfide bridge is formed when a sulfur atom from one cysteine forms a single covalent bond with a sulfur atom from a second cysteine. When a disulfide bridge forms, each cysteine loses one hydrogen atom. The atom count is 11 for a cysteine in mid- chain, but changes to 10 if the cysteine joins with another in a disulfide bridge.
