deoxyribose

(noun)

a derivative of the pentose sugar ribose in which the 2' hydroxyl (-OH) is reduced to a hydrogen (H); a constituent of the nucleotides that comprise deoxyribonucleic acid, or DNA

Examples of deoxyribose in the following topics:

  • DNA and RNA

    • The pentose sugar in DNA is deoxyribose and in RNA it is ribose.
    • The difference between the sugars is the presence of the hydroxyl group on the second carbon of the ribose and hydrogen on the second carbon of the deoxyribose.
    • Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA).
    • Deoxyribose is similar in structure to ribose, but it has an H instead of an OH at the 2′ position.

  • The Structure and Sequence of DNA

    • The components of the nucleotide used in DNA synthesis are a nitrogenous base, a deoxyribose, and a phosphate group .
    • The sugar is deoxyribose in DNA and ribose in RNA.

  • Types of RNA

    • Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA).
    • Deoxyribose is similar in structure to ribose, but it has an H instead of an OH at the 2′ position.

  • History of DNA Research

    • They realized only later that the mixed nucleotides were of two types—one containing ribose (RNA) and the other deoxyribose (DNA).
