The presence of ribose instead of deoxyribose is one difference between RNA and DNA. A Structure for Deoxyribose Nucleic Acid," published in Nature in 1953, the two scientists described the double-helical form of the molecule, shaped like a twisted ladder, in which each rung is made up of four nucleotides: adenine, thymine, cytosine, and guanine (typically abbreviated as A, T, C, and G). The sugar found in DNA is called deoxyribose. This simple sugar was discovered in 1905 by Phoebus Levene, a Russian-born American chemist and pioneer in the study of nucleic acids. Both are pentose sugars, containing 5 carbon atoms, that are numbered 1′ to 5′, the main marks differentiating these positions from the positions of the nitrogenous bases. 3. English: Structure of deoxyribose (as β-D-Desoxyribofuranose) Deutsch: Deoxyribose. Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. The shape of deoxyribose sugar is such that four out of five carbon atoms along with an atom of oxygen form a five membered ring. Chemically, what separates ribose from deoxyribose is that ribose contains an additional oxygen atom. DNA contains thymine rather than uracil as a base. RNA performs a variety of functions in the cell. Moreover, the missing oxygen atom in deoxyribose means that DNA can form its famous double helix shape, making it possible for cells to carry copies of one another. It is probably impossible to build this structure with a ribose sugar in place of the deoxyribose, as the extra oxygen atom would make too close a van del' Waals contact. The previously published X-raydata5•6 on deoxy­ ribose nucleic acid are insufficient for a rigorous test of our structure. It is derived from ribose by the replacement of the hydroxyl group at the two position with hydrogen. Deoxyribose is a simple sugar that participates in the formation of DNA. The structure of deoxyribose in DNA Deoxyribose is an aldopentose, meaning that it is a monosaccharide which contains five carbon atoms, and also contains an aldehyde functional group in its linear structure. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms. This structure has novel features which are of considerable biological interest. If it sounds familiar, that’s because it’s not coincidentally the “D” in “DNA” – deoxyribonucleic acid. c) The phosphate group is attached to the 5’ carbon. Ribose is the sugar found in RNA. The previously published X-ray data ’ 6 on deoxyribose nucleic acid are insufficient for a rigorous test of our structure. Structure Biological Importance.
