Uridine

The chemical structure of uridine

Uridine is a molecule (known as a nucleoside) that is formed when uracil is attached to a ribose ring (also known as a ribofuranose) via a β-N₁-glycosidic bond.

If uracil is attached to a deoxyribose ring, it is known as a deoxyuridine.

Sugarcane extract is rich in nucleosides, especially uridine.{http://www.thebody.com/content/art30244.html}
