If you were to make that change you would find that the molecule now has completely different biological and chemical properties.

如果要做出这样的变化,你会发现,分子的生物形状,和化学性质完全改变了。

And the reason we didn't do that is because we're actually going to spend much of the rest of the course relating these different properties to the properties of molecules in terms of bonding, and also in terms of chemical reactions.

我们至今没有这样做的原因是,实际上我们这门课程以后的大部分时间都将花在,如何将这些性质与分子的性质联系起来,在成键以及化学反应的方面。

But you need to be able to predict what kind of properties a certain atom's going to have within a molecule, whether you're talking about something, for example, that's very electronegative, or something that is not electronegative at all, it is going to make a difference in terms of thinking about how molecules are structured and also how they interact with other molecules.

但是你需要能够预言，什么性质,某个原子在分子中能够具有，无论你讨论的是哪一种情况，比如，它有很高的电负性，还是它根本没有电负性，都将会产生影响,对这个分子的结构,以及与其它分子相互作用的情况。
