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.
