These are highly reactive molecules, such as hydrogen peroxide, that contain oxygen and which can disrupt the normal functioning of cells.

这些是高反应性分子，例化氢，含有气，可以破坏细胞正常功能。

In the early days of my career, my students and I spent a lot of time thinking about the fundamental reactivities of organic molecules and how we could tune their reactivities to create bioorthogonal chemistries.

在我职业涯早期，我和我花了很多时间思考有机分子基本反应性以及我们何调整它们反应性以创建物正交化。
