So a nucleotide attached to one or more phosphate groups is called the Nucleotide. And in most bio and in most biological nucleotides, the phosphate group is attached to the fifth carbon on that sugar. Now, perhaps one of the most prototypical examples the most famous examples of a nucleotide is adenosine five triphosphate or ATP. 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.
