Deoxyuridine

Deoxyuridine is a nucleoside containing uracil. Deoxyuridine differs from uracil in containing a sugar (deoxyribose). Phosphorylation of deoxyuridine produces a nucleotides present on rare occasions in DNA.

Uridine is a related nucleoside that contains ribose instead of deoxyribose as the sugar.
