Adenosine

Adenosine is a nucleoside containing adenine. Adenosine differs from adenine in containing a sugar (ribose). Phosphorylation of adenosine produces a nucleotide found in RNA.

Deoxyadenosine is a related nucleoside. It contains deoxyribose instead of ribose as the sugar. Phosphorylation of deoxyadenosine produces a nucleotide found in DNA.
