• redox reaction
  • ET is a mechanistic description of a redox reaction, wherein the oxidation state of reactant and product changes. (wikipedia.org)
  • The original classical Marcus theory for outer sphere electron transfer reactions demonstrates the importance of the solvent and leads the way to the calculation of the Gibbs free energy of activation, using the polarization properties of the solvent, the size of the reactants, the transfer distance and the Gibbs free energy Δ {\displaystyle \Delta } G0 of the redox reaction. (wikipedia.org)
  • In a redox reaction one partner acts as an electron donor D the other as an acceptor A. For a reaction to take place D and A must diffuse together. (wikipedia.org)
  • Serums
  • Edward Francis (Symptoms, Diagnosis and Pathology of Tularemia, The Journal , Oct. 20, 1928, p. 1155) has called attention to reactions with Brucella abortus in serums from patients with tularemia. (jamanetwork.com)
  • antibodies
  • Purified a-Ro60 antibodies reacted with both peptides and inhibition experiments revealed the specificity of this reaction. (biomedcentral.com)
  • The antibodies which the immune system generates against the M protein may cross-react with heart muscle cell protein myosin, heart muscle glycogen and smooth muscle cells of arteries, inducing cytokine release and tissue destruction. (wikipedia.org)
  • Such cross-reactive carbohydrate determinants (CCDs) are an issue in allergy diagnosis, where about a fifth of all patients displays IgE antibodies against Asn-linked oligosaccharides (N-glycans) containing core α1,3-linked fucose. (wikipedia.org)
  • substitution
  • Chemical reactions may lead to a substitution of a group in a molecule or a ligand in a complex, to the elimination of a group of the molecule or a ligand, or to a rearrangement of a molecule or complex. (wikipedia.org)
  • Assay
  • In an assay for a target nucleotide sequence employing hybridization with a target probe nucleotide sequence, cross reaction between the target probe and a non-target nucleotide sequence, capable of hybridizing with the target probe, is prevented or diminished by introducing, at some point during the hybridization, a non-target probe which hybridizes preferentially with the non-target nucleotide sequence.

  • bonds
  • The aldol addition reaction is one of the most versatile, effective and general methods for the formation of C-C bonds in modern organic synthesis. (organic-chemistry.org)
  • Less than half of the general population experience a reaction with the saturated urushiol alone, but over 90% do so with urushiol that contains at least two degrees of unsaturation (double bonds). (wikipedia.org)
  • transition
  • Conducting transition metal-catalyzed cross-coupling chemistry in water instead of organic solvent has a number of potential benefits in terms of cost, environmental impact, safety, and impurity profiles. (sigmaaldrich.com)
  • One solution applied to a broad range of transition-metal-catalyzed processes is the use of small amounts of a nanomicelle-forming amphiphile in water, which provides a lipophilic medium where cross-coupling reactions can take place. (sigmaaldrich.com)
  • aryl
  • As a synthetic strategy, palladium-catalyzed coupling reactions were used to introduce side chains and aryl substituents into the central heterocycle. (hu-berlin.de)
  • Parallel microscale experimentation was used to develop general conditions for the Suzuki-Miyaura cross-coupling of diversely functionalized primary alkyltrifluoroborates with a variety of aryl chlorides. (organic-chemistry.org)
  • The conditions that were previously identified to promote the cross-coupling of secondary alkyltrifluoroborates with aryl chlorides were not optimal for primary alkyltrifluoroborates. (organic-chemistry.org)
  • species
  • A 3-10% solution of potassium hydroxide (KOH) gives a color change in some species of mushrooms: In Agaricus, some species such as A. xanthodermus turn yellow with KOH, many have no reaction, and A. subrutilescens turns green. (wikipedia.org)
  • catalyst
  • The authors found no aldol product when the reaction was performed in the absence of Lewis base catalyst 4 . (organic-chemistry.org)
  • The catalyst [(π-allyl)PdCl] 2 (2.1 mg, 0.006 mmol, Catalog Number 222380 ), ligand cBRIDP (7.6 mg, 0.022 mmol, Catalog Number 693383 ), KO- t -Bu (184 mg, 1.56 mmol), and amine (1.20 mmol) are sequentially added under argon into a reaction flask containing a stir bar. (sigmaaldrich.com)
  • patients
  • Idiotypic cross-reactions were evaluated in 60 polynucleotide-binding monoclonal lupus autoantibodies produced by human-human hybridomas that were derived from seven unrelated patients with SLE. (rupress.org)
  • The idiotypic cross-reactions of immunoglobulins from unrelated patients suggest that the autoantibodies are derived from related families of germ line genes that are expressed by patients with SLE. (rupress.org)
  • main
  • The challenge raised by nature has stimulated many scientists who, over the last decades, have established the aldol reaction as the main tool to access important synthons for constructing the polyol architecture that is present in many natural products. (organic-chemistry.org)
  • sometimes
  • An example of the confusing serologic reactions which sometimes are obtained may be of interest: A young man developed undulant fever, with the date of onset in June 1936. (jamanetwork.com)
  • partners
  • The scope of the process is extraordinarily broad with respect to both coupling partners, and a preliminary study has established the principle that a high degree of stereochemical control over the reaction can also be exercised via the use of a chiral NHC precursor. (rsc.org)
