释义

Definition of stoichiometric in English:

stoichiometric

adjectiveˌstɔɪkɪə(ʊ)ˈmɛtrɪkˌstɔɪkioʊˈmɛtrɪk
Chemistry
  • 1Relating to stoichiometry.

    〔化〕化学计量学的,元素量法的,关于化学计量学的

    Example sentencesExamples
    • It is necessary to know the main sources of caffeine and CGA content variation in order to predict stoichiometric errors induced by these compounds.
    • It also reacts as a stoichiometric scavenger with organophosphates, thus having the capacity to provide prophylactic protection against highly toxic chemical warfare nerve agents, such as soman and VX.
    • The chemical equations and mechanisms commonplace to stoichiometric chemistry describe only the overall reactions, they do not specify the molecular transformations that place between colliding molecules.
    • Biosynthesis of NO involves oxidation of the guanidine group of arginine with stoichiometric formation of citrulline by the enzyme nitric oxide synthase.
    • In summary, we have developed a reconstitution method that is stoichiometric, functional, and suitable for spectroscopic studies of skeletal muscle.
    1. 1.1 Relating to or denoting quantities of reactants in simple integral ratios, as prescribed by an equation or formula.
      (方程或公式规定的)理想配比的
      a stoichiometric amount of potassium is required for 90% removal of the SO
      Example sentencesExamples
      • The stoichiometric ratio between DNA molecules and microspheres is kept well below one to ensure that the vast majority of microsphere tethers consist of only a single DNA molecule.
      • The extreme pathways of this simple metabolic network can be readily calculated from the stoichiometric matrix.
      • All products were formed in stoichiometric amounts and were accompanied by the consumption of a stoichiometric amount of substrate.
      • The concentration of actin is fixed at 11.9 M, and the amount of scruin is varied to achieve the desired stoichiometric ratio.
      • It should also be noted that upon further addition of either reactant beyond the stoichiometric maximum, the complexes/aggregates are brought back into solution.

Derivatives

  • stoichiometrically

  • adverb
    Chemistry
    • This reaction is catalysed by the enzyme MPT synthase, a heterotetrameric complex of two small and two large subunits, that stoichiometrically converts precursor Z into MPT.
      Example sentencesExamples
      • At low TrpH concentration and high oxygen concentration, the reaction of singlet oxygen with TrpH stoichiometrically produces N-formylkynurenine as a single photoproduct.
      • Pchlide was predominantly under the nonphotoactive state during the first 4 days; and the fast accumulation phase, both types of Pchl accumulated almost stoichiometrically (Fig. lB).
      • Polymyxin B was used as a control agent because it is well known that polymyxins have direct antimicrobial activity and bind stoichiometrically to the lipid A moiety of bacterial LPS.
      • After genome duplication, the retained paralogs may diverge concertedly in sequence and pattern of expression, producing new paralogous network modules unable to interfere stoichiometrically.
