And the way that we name this nucleotide is simply adenosine. Now if this base was Guanine, then we'd call it guanosine. If this was cytosine we'd call it citadine. And if this was uracil, we'd call it uridine. Now if we take and we remove this oh group, then we essentially change our sugar riboseuge into the deoxyribose sugar. And now this would no longer be adenosine, it would be deoxy adenosine.
