The term "2-deoxyribose" may refer to either of two enantiomers: the biologically important d-2-deoxyribose and to the rarely encountered mirror image l-2-deoxyribose. [3] d-2-deoxyribose is a precursor to the nucleic acid DNA. 2-deoxyribose is an aldopentose, that is, a monosaccharide with five carbon atoms and having an aldehyde functional group.
L-Ribose Fischer Projection. Ribose is a simple sugar and carbohydrate with molecular formula C 5 H 10 O 5 and the linear-form composition H−(C=O)−(CHOH) 4 −H. The naturally occurring form, d-ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes.
Deoxyribose, or 2-deoxy-D-ribose, a constituent of DNA; Fucose, or 6-deoxy-L-galactose, main component of fucoidan of brown algae, and present in N-linked glycans; Fuculose, or 6-deoxy-L-tagatose, one of the important components of avian influenza virus particles; Rhamnose, or 6-deoxy-L-mannose, present in plant glycosides
These prefixes are attached to the systematic name of the molecular graph. So for example, D-glucose is D-gluco-hexose, D-ribose is D-ribo-pentose, and D-psicose is D-ribo-hexulose. Note that, in this nomenclature, mirror-image isomers differ only in the ' D '/' L ' prefix, even though all their hydroxyls are reversed.
Ribose [2] Rice syrup [1] Rhamnose [2] Saccharose [1] Sorghum syrup [1] Sucrose [1] – often called white sugar, granulated sugar, or table sugar, is a disaccharide chemical that naturally contains glucose and fructose. Commercial products are made from sugarcane juice or sugar beet juice. Sugarcane, which contains a high concentration of sucrose
Ribose is a constituent of RNA, and the related molecule, deoxyribose, is a constituent of DNA. Phosphorylated pentoses are important products of the pentose phosphate pathway , most importantly ribose 5-phosphate (R5P), which is used in the synthesis of nucleotides and nucleic acids , and erythrose 4-phosphate (E4P), which is used in the ...
