• While carbamic acids are unstable, many carbamate esters and salts are stable and well known. (wikipedia.org)
  • The salt ammonium carbamate is generated by treatment of ammonia with carbon dioxide: 2 NH3 + CO2 → NH4[H2NCO2] Carbamate esters also arise via alcoholysis of carbamoyl chlorides: R2NC(O)Cl + R'OH → R2NCO2R' + HCl Alternatively, carbamates can be formed from chloroformates and amines: R'OC(O)Cl + R2NH → R2NCO2R' + HCl Carbamates may be formed from the Curtius rearrangement, where isocyanates formed are reacted with an alcohol.

  • Honey bees (Apis mellifera) are exposed to sublethal doses of insecticides, but little is known about insecticide effects on their survivorship associated to health-related gene expression. (geneticsmr.com)
  • To test the effect of sublethal doses of clothianidin, imidacloprid and carbaryl on the lifespan and health of honey bees, workers were orally and topically exposed to LD5 doses of these insecticides. (geneticsmr.com)
  • RCON3 → RNCO + N2 RNCO + R′OH → RNHCO2R′ Within nature carbon dioxide can bind with neutral amine groups to form a carbamate, this post-translational modification is known as carbamylation. (wikipedia.org)
  • The carbamate is formed when an uncharged lysine side chain near the ion reacts with a carbon dioxide molecule from the air (not the substrate carbon dioxide molecule), which then renders it charged, and, therefore, able to bind the Mg2+ ion. (wikipedia.org)
  • Although not usually isolated as such, the salt ammonium carbamate is produced on a large scale as an intermediate in the production of the commodity chemical urea from ammonia and carbon dioxide. (wikipedia.org)
  • Therefore, it is concluded that resistance to insecticides in B . tabaci in the state of Sinaloa is due to the high content of α - β-esterases and oxidases, while acetylcholinesterase is not a relevant mechanism in the populations of this producing region. (gob.mx)

  • Here, using RNA interference library screening and subsequent in vivo studies, the functional significance of ERK1/2 activation in CA-induced Stc2-mediated protection against acute ethanol-induced apoptosis was identified. (bvsalud.org)
  • Using ex vivo, in vivo and clinical approaches, we investigated the functional effects of plasminogen on the widely used FAD, Abeta42 oligomer or Tau intracranial injection-induced AD mouse model and explored its therapeutic effects on patients with AD. (inra.fr)
  • We have previously shown that a bona fide aryl hydrocarbon receptor (AhR) agonist, cinnabarinic acid (CA), protects against alcohol-induced hepatocyte apoptosis via activation of a novel AhR target gene, stanniocalcin 2 (Stc2). (bvsalud.org)
  • 6. These data suggest that systemic injection of the 5-HT6 antagonist, Ro 04-6790, produces a stretching behaviour that appears to be mediated by an increase in cholinergic neurotransmission in the CNS and which could be a useful functional correlate for 5-HT6 receptor blockade.

  • Polymers whose repeat units are joined by carbamate like groups −NH−C(=O)−O− are an important family of plastics, the polyurethanes. (wikipedia.org)
  • The N-terminal amino groups of valine residues in the α- and β-chains of deoxyhemoglobin exist as carbamates. (wikipedia.org)
  • The ε-amino groups of the lysine residues in urease and phosphotriesterase also feature carbamate. (wikipedia.org)
  • Polyurethanes contain multiple carbamate groups as part of their structure. (wikipedia.org)
  • Typically, polyurethane polymers are made by combining diisocyanates, e.g. toluene diisocyanate, and diols, where the carbamate groups are formed by reaction of the alcohols with the isocyanates: RN=C=O + R′OH → RNHC(O)OR′ The so-called carbamate insecticides feature the carbamate ester functional group. (wikipedia.org)
  • the term "urethane links" describe how carbamates polymerize. (wikipedia.org)
  • Weakness is loss of muscle strength, although many patients also use the term when they feel generally fatigued or have functional limitations (eg, due to pain or limited joint motion) even though muscle strength is normal. (msdmanuals.com)
