, Pentoses – Sugars of DNA
Pentose monosaccharides contain five carbon atoms. Like
hexoses, pentoses are long enough to form a ring.
Two important pentose molecules are the structural isomers
ribose and deoxyribose. These are important constituents
of RNA and DNA.

The only difference between them is that ribose has one
H atom and one –OH group attached to carbon 2,
whereas deoxyribose has 2 H atoms and no –OH group.
