This is, let's say, some type of integral transmembrane protein. And this is a peripheral protein that contains a carbohydrate component. So this is an example of glycoprotein. So we have a glycoprotein, a transmembrane protein. We have these phospholipids, in which case we have two types of phospholipids. We have those phosphoglycerides as well as finolipids, which we spoke of previously.
