| disulfide bond | A single bond between two sulfurs; specifically, the -S-S- link binding two peptide chains (or different parts of one peptide chain); also occurs as part of the molecule of the amino acid, cystine, and is important as a structural determinant in many protein molecules, notably keratin, insulin, and oxytocin. A symmetric disulfide is R-S-S-R; R'-S-S-R is a mixed disulfide. (05 Mar 2000) |

| disulfide bridge | A disulfide linkage between two cysteinyl residues in a poly-or oligopeptide or in a protein, any disulfide linkage between any thiol-containing moieties of a larger molecule. Synonym: cystine bridge. (05 Mar 2000) |
| tetraethylthiuram disulfide | <chemical> A carbamate derivative used as an alcohol deterrent. It is a relatively nontoxic substance when administered alone, but markedly alters the intermediary metabolism of alcohol. When alcohol is ingested after administration of disulfiram, blood acetaldehyde concentrations are increased, followed by flushing, systemic vasodilation, respiratory difficulties, nausea, hypotension, and other symptoms (acetaldehyde syndrome). The intensity and duration of symptoms vary greatly from individual to individual. Pharmacological action: alcohol deterrents. Chemical name: Thioperoxydicarbonic diamide (((H2N)C(S))2S2), tetraethyl- (12 Dec 1998) |
| lipoamide disulfide | Oxidised lipoic acid in amide combination with the &vepsilon;-amino group of an l-lysyl residue of pyruvic acid dehydrogenase. (05 Mar 2000) |
