Isotope effects
基本例句
同位素效应
Measurement of kinetic isotope effects indicated that the rate-limiting step of these reactions is the C-H bond cleavage.动力学同位素效应测量表明限速步骤;这些反应是在C-八键裂解.
The authors propose an E 2 elimination mechanism in which the cinchona alkaloid acts as a chiral base in consistency with measured isotope effects.作者提出了电子二是淘汰机制金鸡生物碱手基地作为衡量符合同位素效应.
We have used the primary deuterium and solvent kinetic isotope effects to determine the relative cleavage timing of the glucose OH1 and CH1 bonds in GOOX.本论文也利用基质同位素效应与溶剂同位素效应，藉以分析葡萄寡糖氧化酶反应时，葡萄糖CH1与OH1键结断裂的可能顺序。
Based on density-functional theory and density-functional perturbation theory we have discussed systematically the hydrogen isotope effects on the thermodynamic properties of TiX2 system.应用基于密度泛函理论和密度泛函微扰理论的 PWSCF和PHONONS第一原理计算程序系统研究了TiX2系统热力学特性的同位素效应。
The decreased activity by 50 fold and the kinetic isotope effects show that CH1 bond cleavage is more rate-limited in the Y429F mutant, consistent with the proposed proton shuttling by Tyr429.其中Y429F突变株酵素活性下降约50倍，且从其动力学同位素效应结果显示，Y429的突变使CH1键结断裂的速率更受到限制，乃符合Y429作为活性中心碱基之推测。 |
