A sugar derived from ribose by replacement of a hydroxyl group by hydrogen.
Chemical formula; C₅H₁₀O₄. There are several isomers; the isomer 2-deoxyribose is a constituent of DNA
- ‘Sugars are vital components of life, e.g. the 5-carbon sugars ribose and deoxyribose are part of the skeletons of our information storage molecules, RNA and DNA respectively.’
- ‘For example, ribose and deoxyribose are essential for the formation of the backbone of RNA and DNA.’
- ‘Another difference between DNA and RNA is that RNA contains ribose, rather than deoxyribose.’
- ‘Each nucleotide is composed of deoxyribose (a type of sugar), a phosphate group, and one of four nitrogen-containing bases.’
- ‘The backbone of both strands in the double helix is a chain of linked phosphate and deoxyribose molecules.’
