Deoxyribose is a
pentose (5-carbon) sugar - formula C
5H
10O
4.
It is found in
DNA.
Notice the
5 carbon atoms (grey) forming the backbone of the molecule, and the
oxygen atom (red) in the ring - which is a 5 sided ring, unlike glucose.
The hydrogen atoms (white) are either attached directly to the carbons, or via oxygen as OH groups - at an angle.
The carbon outside the ring has 2 single hydrogens and an OH group.
Deoxyribose differs from ribose in that it lacks an oxygen at carbon 2 (labelled) - and so has only
2 hydrogen atoms (white).
