We'll see why they have to separate that in a minute, but they do that these lipid bi-layers solve that problem for them and they're self-assembled structures from these molecules called phospholipids.

我们马上会讲到为什么要把它们隔离开,脂质双层膜解决了这个问题,而这些自主装结构,就是由磷脂分子组成的

Well instead of forming droplets like fat they arrange in a very particular way, they form these structures that are called self-assembled structures because they occur naturally, because of properties of the lipids.

它们不是像脂肪一样形成液滴,而会细致地排列起来,它们形成的结构名为,自组装结构,因为它们能够自然生成,这归功于这种脂质的特性
