Disulfide - Wikipedia
In chemistry, a disulfide (or disulphide in British English) is a compound containing a R−S−S−R′ functional group or the S 2− 2 anion. The linkage is also called an SS-bond or sometimes a disulfide bridge and usually derived from two thiol groups.
Carbon disulfide - Wikipedia
Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S. It is also considered as the anhydride of thiocarbonic acid . [ 8 ] It is a colorless, flammable, neurotoxic liquid that is used as a building block in organic synthesis.
Disulfide - an overview | ScienceDirect Topics
Disulfides are compounds with the general formula R S S R′. These compounds are more stable than the corresponding peroxides that contain the O O group. When the R and R′ are aliphatic radicals with two to five carbons, these compounds decompose in the range of temperatures from 300°C to 500°C. The reaction products include H 2 S, R SH ...

A disulfide species refers to a protein with a particular pairing of cysteines in disulfide bonds, while a disulfide ensemble is any collection of disulfide species.
Disulfide Bond - an overview | ScienceDirect Topics
A disulfide bond is a post-translational modification that covalently links the sulfur atoms of two cysteine residues in close spatial proximity so that proteins are internally or externally cross-linked. From: Computational and Structural Biotechnology Journal, 2020

Apr 23, 2020 · Disulfide bonds are a central structural element which stabilizes the mature proteins' 3D structure and/or exhibit physiologically relevant redox activity (Bosnjak et al., 2014). They are mostly found in secretory proteins and extracellular domains of membrane proteins.
15.7: Redox Reactions of Thiols and Disulfides
Jul 20, 2022 · A disulfide bond is a sulfur-sulfur bond, usually formed from two free thiol groups. The interconversion between dithiol and disulfide groups is a redox reaction: the free dithiol form is in the reduced state, and the disulfide form is in the oxidized state.
