  • hydrogen peroxide
  • Diallyl disulfide can be readily oxidized to allicin with hydrogen peroxide or peracetic acid. (wikipedia.org)
  • Typical oxidants are chlorine and hydrogen peroxide: 2 R2NCSSNa + Cl2 → (R2NCSS)2 + 2 NaCl Thiuram disulfides react with Grignard reagents to give esters of dithiocarbamic acid, as in the preparation of methyl dimethyldithiocarbamate: [Me2NC(S)S]2 + MeMgX → Me2NC(S)SMe + Me2NCS2MgX The compounds feature planar dithiocarbamate subunits and are linked by an S−S bond of 2.00 Å. (wikipedia.org)
  • The structure of hydrogen disulfide is similar to that of hydrogen peroxide, with C2 point group symmetry. (wikipedia.org)
  • hydrogenation
  • Although the hydrogenation of disulfides is usually not practical, the equilibrium constant for the reaction provides a measure of the standard redox potential for disulfides: RSSR + H2 → 2 RSH This value is about −250 mV versus the standard hydrogen electrode (pH = 7). (wikipedia.org)
  • reaction
  • The overall vectorial electron transfer reaction catalyzed by DsbD is: 2 e− cytoplasm → 2 e− periplasm DsbB contains 4 essential cysteine residues, reversibly forming two disulfide bonds. (wikipedia.org)
  • DsbC
  • Although DsbA displays no proofreading activity for repair of wrongly paired disulfides, DsbC, DsbE and DsbG have been found to demonstrate proofreading activity. (wikipedia.org)
  • isomerase
  • Disulfide-Bond Isomerase Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 216 amino acids (21-236) and having a molecular mass of 23.5 kDa. (prospecbio.com)
  • DsbA
  • Oxidoreductase Redox Disulfide DsbA Transporter Classification Database TCDB: 5.A.1 The Disufide Bond Oxidoreductase D (DsbD) Family Bardischewsky, F. (wikipedia.org)
  • alkali
  • Intercalation can be conducted by combining a suspension of the disulfide material and a solution of the alkali metal in anhydrous ammonia. (wikipedia.org)
  • selenium
  • Selenium disulfide is a medication used to treat pityriasis versicolor, seborrhoeic dermatitis, and dandruff. (wikipedia.org)
  • Selenium disulfide was approved for medical use in the United States at least as early as 1951. (wikipedia.org)
  • Selenium disulfide is available as a generic medication and over the counter. (wikipedia.org)
  • Selenium disulfide is sold as an antifungal agent in shampoos for the treatment of dandruff and seborrheic dermatitis associated in the scalp with Malassezia genus fungi. (wikipedia.org)
  • At the 2.5% strength, selenium disulfide is also used on the body to treat tinea versicolor, a type of fungal skin infection caused by a different species of Malassezia. (wikipedia.org)
  • Selenium disulfide can cause discoloration of the hair and alter the color of hair dyes. (wikipedia.org)
  • Selenium disulfide has a composition that approximates to SeS2 and is sometimes called selenium sulfide. (wikipedia.org)
  • Zinc pyrithione, an antimicrobial agent used in many off the shelf shampoos Selsun Blue, a shampoo with selenium disulfide as its active ingredient Ketoconazole, another antifungal agent used in medicated shampoos WHO Model Formulary 2008 (PDF). (wikipedia.org)
  • Thus
  • Thus, Alliaceae plants have likely developed the diallyl disulfide-TRPA1 protection mechanism against predators at the early stages of the evolution. (wikipedia.org)
  • Molecular
  • in contrast, the high-molecular-weight glutenins are formed by disulfide linkages of several diverse polypeptide chains which have been separated and characterized. (springer.com)
  • bond
  • In chemistry , a disulfide bond is a single covalent bond derived from the coupling of thiol groups. (wikidoc.org)
  • The linkage is also called an SS-bond or disulfide bridge. (wikidoc.org)
  • A disulfide bond is typically denoted by hyphenating the abbreviations for cysteine, e.g., the "Cys26-Cys84 disulfide bond", or the "26-84 disulfide bond", or most simply as "C26-C84" where the disulfide bond is understood and does not need to be mentioned. (wikidoc.org)
  • Since water molecules attack amide-amide hydrogen bonds and break up secondary structure , a disulfide bond stabilizes secondary structure in its vicinity. (wikidoc.org)
  • For example, researchers have identified several pairs of peptides that are unstructured in isolation, but adopt stable secondary and tertiary structure upon forming a disulfide bond between them. (wikidoc.org)
  • In chemistry, a disulfide 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. (wikipedia.org)
  • The disulfide bonds are strong, with a typical bond dissociation energy of 60 kcal/mol (251 kJ mol−1). (wikipedia.org)
  • However, being about 40% weaker than C−C and C−H bonds, the disulfide bond is often the "weak link" in many molecules. (wikipedia.org)
