We'll find it most of the time. Now, both types of phospholipids, these phosphoglycerides and fingal lipids, are antipathic molecules. And what that means is they have a nonpolar component and they have a polar component. So basically, the fatty acids give the phospholipids, the hydrophobic non polar properties. But it's these two groups, the phosphate and the alcohol, that give them the water loving hydrophilic polar quantities and so qualities. And so that's exactly why we call phospholipids amphipathic, because they have groups that can associate with polar and non polar environments.
