deoxyribose
n 1: a sugar that is a constituent of nucleic acids

The Collaborative International Dictionary of English v.0.48 (gcide)

deoxyribose \deoxyribose\ n.
a pentose ({C5H10O4}) in which one of the hydroxyl groups of
ribose has been replaced by a hydrogen. In deoxyribonucleic
acids, the deoxyribose is {D-2-deoxyribose}, in which the
hydroxyl at the 2 position of ribose is the one which is
replaced by hydrogen.

Deoxyribose - Wikipedia
Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H− (C=O)− (CH 2)− (CHOH) 3 −H Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of a hydroxy group
Deoxyribose | DNA, Nucleic Acids, Sugars | Britannica
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)

Difference Between Deoxyribose And Ribose - GeeksforGeeks
Ribose sugar has a hydroxyl group on 2nd carbon whereas deoxyribose sugar has a hydrogen atom on 2nd carbon Also, deoxyribose is a constituent of DNA whereas ribose sugar is a constituent of RNA
Deoxyribose - Definition and Structure | Biology Dictionary
Deoxyribose is the five-carbon sugar molecule that helps form the phosphate backbone of DNA molecules DNA, or deoxyribonucleic acid is a polymer formed of many nucleic acids Each nucleic acid is composed of a deoxyribose molecule bound to both a phosphate group and either a purine or a pyrimidine
Deoxyribose Sugars: The Backbone of DNA - Biology Insights
Deoxyribose sugars are a primary component of deoxyribonucleic acid (DNA) They form the sugar-phosphate backbone of the DNA double helix Each deoxyribose molecule links to a phosphate group and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), or thymine (T)
Why Does DNA Use Deoxyribose Instead of Ribose?
In deoxyribose, the 2′ carbon atom is bonded to a hydrogen atom, meaning it lacks a hydroxyl (-OH) group at this position The absence of the oxygen atom makes deoxyribose less reactive This reduced reactivity contributes to the chemical inertness of the DNA backbone
Deoxyribose - Laboratory Notes
In DNA structure, deoxyribose plays a central role by linking nitrogenous bases (adenine, guanine, cytosine, or thymine) to phosphate groups, forming nucleotides, the building blocks of DNA
Deoxyribose - Simple English Wikipedia, the free encyclopedia
Deoxyribose is the sugar component of deoxyribonucleic acid or DNA, having one less hydroxyl group than ribose, the sugar component of ribonucleic acid or RNA Due to its various attributes it has numerous appellations ie d-2-deoxyribose, a five carbon monosaccharide, and pentose sugar Deoxyribose is most notable for its presence in the DNA
