  • Both sugars have a five-membered ring structure, formed by carbon atoms and one oxygen atom.
    Each carbon atom (except one) is bonded to a hydroxyl group uno online (OH).

  • The molecular formula of a compound gives us the idea about the elements that make up the particular compound, and the number of atoms of each element present in the compound. The molecular formula of ribose is C5H10O5. The molecular formula of deoxyribose is C5H10O4.

    Similarities

    Ribose and deoxyribose are both monosaccharides or simple sugars.

    Both are aldopentoses, which means both are pentose sugar molecules which, in their open-chain form, have an aldehyde functional group at one end. A pentose sugar is one that is made up of 5 carbon atoms.

    Differences

    While a molecule of ribose has 5 oxygen atoms, a molecule of deoxyribose has only 4 oxygen atoms.

  • The 5-carbon sugars ribose and deoxyribose are important components of nucleotides, and are found in RNA and DNA, respectively. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms. ... Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy").
