In the biochemical reactions that are taking place in your body, there is equilibrium between a whole myriad of reactants and products, and thank heavens that gets maintained.

在我们身体内进行的,生物化学反应中，大量的反应物和产物,也是处于平衡状态，谢天谢地实际情况就是这样。

So, that's kinetics -- how fast a reaction will go, and from the perspective of someone who's a biochemist, I'm interested in kinetics and enzyme kinetics, and thinking about molecules that catalyze reactions in the body.

所以这就是动力学，一个反应发生的有多快,从一个生物化学家的角度,我喜欢研究动力学,酶动力学。

if we have a very electronegative atom within a certain molecule, what you'll actually find is that it does affect how the molecule is going to take place or take part in different chemical or biological reactions.

如果在某个分子中有一个电负性很高的原子，你会发现它确实会影响到,这个分子所起的作用,在不同的化学反应或者生物反应中时。
