/dee ok'si ruy"bohs/, n. Biochem.
1. any of certain carbohydrates derived from ribose by the replacement of a hydroxyl group with a hydrogen atom.
2. the sugar, HOCH2(CHOH)2CH2CHO, obtained from DNA by hydrolysis.
[1930-35; DEOXY- + RIBOSE]

also called  d-2-deoxyribose 

      five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases. The presence of deoxyribose instead of ribose is one difference between DNA and RNA (ribonucleic acid). Deoxyribose was synthesized in 1935, but it was not isolated from DNA until 1954.
