Water molecules contain a partial positive charge on the hydrogen ions. And what that means when these Agrican molecules are in their initial position, we'll see that a bunch of water molecules will be absorbed and attached onto these glycosaminoglycans. The red ones are the conroytin sulfates and the brown ones are the keratin sulfates. And so we're going to have non covalent interactions between the water molecules and these glycosaminoglycans. So we see that the glycosaminoglycans, as a result of their negative charge, they will be able to actually absorb the water molecule. And so this section will be lubricated with water.
