So basically we can diversify the capabilities and the functionality of proteins and lipids by basically attaching sugar components onto these macromolecules. So by combining sugars and proteins and sugars and lipids and so forth, we can basically increase the capabilities of these molecules. For instance, we already spoke about an important glycoprotein when we discussed the coagulation cascade. So we discussed the tissue factor. So we said that the tissue factor is basically a glycoprotein. So this is shown in green and this is, let's say, the cell membrane of some endothelial cell found in the blood vessel.
