The sugar found in the side chains of DNA, differing from ribose in having a hydrogen atom instead of an OH group on one of its carbon atoms. Chemical formula: C5H10O4.
five-carbonfive-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.
