We're going to talk about this kind of non-covalent interaction more when we talk about the immune system, because one example of ligand and receptors that's important in the immune system are antigens - foreign molecules, and antibodies - molecules that we produce.

当我们讲到免疫系统的时候,会更详细地谈到这种非共价化合反应,因为在免疫系统中,一个重要的配体受体结合反应,就是抗原,即外源分子,与抗体,这个人体自身产生的分子结合
