So if we take a look at the following molecule so if this base is, let's say, adenine, then this molecule would be that ATP molecule that we spoke of earlier. So we have the triphosphate group, we have that nitrogenous base and these two groups are essentially connected to one another as a result of this sugar. So this is a ribosugar that bridges these two molecules. And every single RNA molecule basically contains this group here, this unit. Now, the next function of sugars, the next role that sugar is actually playing organisms and this includes inside our own bodies is using sugars to basically modify lipids and proteins. And we'll discuss this in much more detail in the next several lectures.
