您要查找的是不是:
- homolytic bond cleavage 均裂
- The energy is dissipated by subsequent bond cleavage reactions into various "daughter ions". 这种能量消耗在后续的键断裂成各种“子离子”的反应中。
- Other nucleophiles such as C_6H_5S~-, RCO_2~- (B. = CH_3, CF_3) reacted with 1 giving only the products of S-O bond cleavage. 其它亲核试剂如RCO_2~-、ArS~-等却只进攻1的硫原子.
- Measurement of kinetic isotope effects indicated that the rate-limiting step of these reactions is the C(sp 2 )-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(藻2)-八键裂解.
- The detection of 2-methylcyclohexane in the HDN of MCHA explains the C(sp3)-N bond cleavage showing that MCH is formed via nucleophilic substitution of the amine group of MCHA. 通过检测MCHA中的甲基环己烷(MCH),解释C(sp~3)-N键断裂是由于MCHA中的胺基被亲核取代。
- 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。
