Deoxyribose

Definition

noun

(1) An aldopentose (i.e. a monosaccharide with five carbon atoms) derived from the pentose sugar ribose by the replacement of a hydroxyl group with a hydrogen atom at the 2 position, leading to the net loss of an oxygen atom (hence the name).

(2) The sugar component in the side chains of DNA, in contrast to the ribose in the side chains of RNA.

RNA as genetic material

... RNA is a single-stranded molecule in many of its biological roles and has a much shorter chain of nucleotides. Second, while DNA contains deoxyribose, RNA contains ribose (in deoxyribose there is no hydroxyl group attached to the pentose ring in the 2' position). These hydroxyl groups ...
