There is generally 1 carbohydrate found in nucleic acids. That is the 5 carbon Aldose sugar called Ribose.

RNA has a ribose sugar.

If you remove the hydroxyl group on the second carbon of Ribose, you get something called 2`-dexoyribose. This is still Ribose, but is missing its OH group at carbon 2. This is the sugar used in DNA.

RNA has a Ribose sugar, DNA has a 2`-deoxyribose sugar. Both are ribose, but technically speaking they are different.

The two carbohydrates found in nucleic acids are the 5-carbon sugars deoxyribose and ribose.


The sugar deoxyribose is found in DNA (deoxyribo nucleic acid), and the sugar ribose is found in RNA (ribo nucleic acid).

Deoxyribose has one less oxygen atom in the molecule than ribose, hence de-oxy.

The molecular formula for deoxyribose is #"C"_5"H"_10"O"_4"#, and the molecular formula for ribose is #"C"_5"H"_10"O"_5"#. Note that the formula for deoxyribose has one less oxygen atom than ribose.
