Deoxy sugar

Comparison of the chemical
structures of ribose (top)
and deoxyribose (bottom).

Deoxy sugars ^[1] are sugars that have had a hydroxyl group replaced with a hydrogen atom.

Examples include:

Deoxyribose, or 2-deoxy-D-ribose, a constituent of DNA
Fucose, or 6-deoxy-L-galactose, main component of fucoidan of brown algae, and present in N-linked glycans
Rhamnose, or 6-deoxy-L-mannose, present in plant glycosides
