More strictly, a molecule whose pharmacological activity can be correlated with its chemical structure.

更严格地说是药学活性可以和化学结构相关联的分子。

What this is telling us is that we just have a chemical potential, of Helmholtz free energy per molecule.

这告诉我们的是，我们只有化学势，每个分子的亥姆霍兹自由能。

A hydrogen molecule is then added to the fat. This hydrogenation process alters the chemical structure of the fat.

在脂肪中加入氢分子，这个加氢的过程改变了脂肪的化学结构。

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。

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。

So, in talking about covalent bonds, we should be able to still apply a more general definition of a chemical bond, which should tell us that the h 2 molecule is going to be lower in energy than if we looked at 2 separate hydrogen atom molecules.

那么，既然提到了共价键，我们应该还可以,给化学键下一个更普遍的定义,那就是告诉我们氢分子能量应该更低,与两个分开的氢的单原子分子相比。
