Cells are surrounded by membranes, thin sheets made up of a double layer of molecules that separate the inside of the cell from its environment. These molecules, lipids, have water-loving headgroups and oily tails, so that the membrane has an oil-like interior. Lung surfactant, a single layer of lipids, forms the interface between air and tissue in the lungs, with the tails pointing at the air.

细胞被膜包围着，膜是由双层分子组成的薄片，将细胞内部与环境隔离开来。这些分子，即脂质，具有亲水的头群和油性尾部，因此膜具有油状的内部。肺表面活性剂是一层脂质，它形成了肺中空气和组织之间的界面，尾部指向空气。
