So this is the molecule that our cells and our body uses to basically store and generate energy for different types of cellular processes. So in this particular case, the sugar is a ribose sugar because we have that oh, group on the second carbon. Notice that our base, just like in this case, is Adenine. And here, unlike here, we have the phosphate groups. And for ATP, we have one, two, three of these phosphate groups. And so we have a negative charge here, a negative charge delocalized here and two negative charges delocalized among those three oxygen atoms.
