They have two fatty acid chains and so these are the oily like parts of the molecule, the molecules that behave like oil.

The fascinating part about this layer is that it solves the problem for phospholipids about how to exist in water when half of you wants to be in oil, and that the water soluble part of the top leaflet here, of the top points up into the water, and the fatty acid chains point down.
这层膜的迷人之处在于,它解决了磷脂,如何存在于水中和油脂中的问题,水溶性的顶端部分,向上插入水中,而脂肪链则指向下
