Consensus Reports

Ribose, primarily occurring as D-ribose, is an organic compound that occurs widely in nature. Ribose is an aldopentose, that is a monosaccharide containing five CARBON atoms that, in its acyclic form, has an aldehyde functional group at one end. Typically, this species exists in the cyclic form, as depicted in the upper right. It was first reported in 1891 by Emil Fischer. It comprises the backbone of RNA, a biopolymer that is the basis of genetic transcription. It is related to deoxyribose, as found in DNA, by the removal of one hydroxy group. Once phosphorylated, ribose can become a subunit of ATP, NADH, and several other compounds that are critical to metabolism.

Specification

The IUPAC name of D-Ribose is (3R,4S,5R)-5-(hydroxymethyl)oxolane-2,3,4-triol. With the CAS registry number 50-69-1, it is also named as Ribo-2,3,4,5-tetrahydroxyvaleraldehyde, D-. The product's categories are Fine Chemical & Intermediates; Sugars, Carbohydrates & Glucosides; Basic Sugars (Mono & Oligosaccharides); Biochemistry; Nucleosides, Nucleotides & Related Reagents; Ribose; Riboses and 2'-Deoxyriboses; Carbohydrates & Derivatives; Alphabetical Listings; Flavors and Fragrances; Q-Z; Biochemicals Found in Plants; Metabolic Pathways; Metabolites and Cofactors on the Metabolic Pathways Chart, and the other registry numbers are 58-91-3; 6915-40-8; 93781-19-2. Besides, it is white powder, which should be stored in closed and cool place at 2-8 °C. In addition, its molecular formula is C5H10O5 and molecular weight is 150.13.
