反应速率

How to quantitatively determinate the relation between system behaviors and parameters variations was an important problem of systems biology.In order to study robustness of NF-κB signal transduction networks,the parameters of system model were assigned to subject to stochastic distributions.

然而，包括速率常数和反应物初始浓度在内的许多参数都是通过实验测量或者根据文献推断得到的，即使对于那些完全通过实验来估计参数的模型，也不能确定参数的实际值与对应的生物系统是否完全一致。

In general, dilution of the reagents can increase, decrease, or have no effect on the reaction rate.

在一般情况下，试剂的稀释可能对反应的速率增加，减少，或没有影响。

Rate constant of ONOO〓 formation, which is access to diffusion-controlled limit, is as three times as that of dismutation of O〓〓· by superoxide dismutase, and much faster than that of reaction of NO with hemecontaining proteins, thus demonstrating that ONOO〓 can form as long as NO meets O〓〓· during their diffusion in biological milieu.

ONOO〓在体内生成有较充分的理论依据。ONOO〓的生成速率接近于受控制的弥散极限，比超氧化物歧化酶歧化O〓〓·的速度快3倍，远远超过NO与血红素蛋白的反应速度。
