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

这反应性分子，例如过氧化氢，含有氧气，可以破坏细胞的正常功能。

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.

在我职业生涯的早期，我和我的学生花了很多时间有机分子的基本反应性以及我们如何调整它们的反应性以创建生物正交化学。
