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.

The amino acid cystine, a disulfide, is an important component of many proteins; the sulfur-sulfur bond plays a key role in maintaining the molecules in shapes (so-called tertiary structures) essential for their biological activity.

Disulfide bonds, also known as disulfide bridges, are covalent bonds formed between two sulfur atoms. They are created through the oxidation of thiol groups (–SH) from cysteine residues in proteins.

The meaning of DISULFIDE is a compound containing two atoms of sulfur combined with an element or radical.

2022年7月20日 · 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.

Other articles where disulfide is discussed: organosulfur compound: Disulfides and polysulfides and their oxidized products: A unique property of sulfur is the ability to form chains of sulfur atoms with organic groups at either end—e.g., RSnR′, where n can range from 2 to 20 or more.

diphenyl disulfide at —200 °C leads to the formation of a radical product, the EPR spectrum of which is characterised by an axially anisotropic g-factor. This is apparently due to the localisation of the unpaired electron on the sulfur atom in the PhS" radical. The absorption spectrum of this radical contains bands at 355 and

2020年1月26日 · A disulfide bond, also called an S-S bond, or disulfide bridge, is a covalent bond derived from two thiol groups. In biochemistry, the terminology R-S-S-R connectivity is commonly used to describe the overall linkages.

Disulfide linkages (–S–S–) between protein chains are extremely important in protein structure. Thioethers, which are sulfur analogs of ethers, have the form general formula RSR′. An example is dimethylsulfide (CH 3 SCH 3), which is responsible for the sometimes unpleasant odor of cooking cabbage and related vegetables. Note that ...

2022年2月28日 · No headers A disulfide is a compound that has the following general structural formula. R 1 and R 2 could be alkyl groups, aryl groups, or any combination thereof; in most disulfides, R 1 = R 2. eg: The S—S group in an organic molecule is called the disulfide group.
