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. We have the glycolipid, which we spoke about here, and we also have these cholesterol molecules. So notice that the hydroxyl group shown in orange basically interacts with these blue heads of the nearby phospholipids. And these hydroxyl groups basically points toward the aqueous environment either into the cell or out of the cell.
