Structural Biochemistry/Chemical Bonding/ Disulfide bonds

In biochemistry, a disulfide (or disulphide in British English) refers to a functional group with the structure R−S−S−R′. The linkage is also called an SS-bond or sometimes a disulfide bridge and is usually derived by the coupling of two thiol groups. In biology, disulfide bridges formed between thiol groups … See more Symmetrical disulfides are compounds of the formula R2S2. Most disulfides encountered in organo sulfur chemistry are symmetrical disulfides. Unsymmetrical disulfides (also called heterodisulfides) are compounds of the … See more The disulfide anion is S 2, or S−S . In disulfide, sulfur exists in the reduced state with oxidation number −1. Its electron configuration then resembles that of a chlorine atom. It thus tends to form a covalent bond with another S center to form S 2 group, … See more Rubber manufacturing The vulcanization of rubber results in crosslinking groups which consist of disulfide (and polysulfide) bonds; in analogy to the role … See more • Media related to Disulfides at Wikimedia Commons See more Occurrence in proteins Disulfide bonds can be formed under oxidising conditions and play an important role in the folding and stability of some proteins, usually … See more Thiosulfoxides are orthogonally isomeric with disulfides, having the second sulfur branching from the first and not partaking in a continuous chain, i.e. >S=S rather than −S−S−.
