Now, all these blue molecules, so these blue molecules with these two purple regions, these are the phospholipids. So we have the phosphate group, showed in blue. And these purple regions are basically those fatty acids. Now, these guys here are basically our glycolipids. So some glycolipids, let's say, contain two sugar molecules, others contain more sugar molecules, as shown here. So the, this is the sugar moiety of this glycolipid.
