Figure 8.22 shows the only two sugars which occur in nucleic acids: β-d-ribose in RNA and β-d-2-deoxyribose in DNA These sugars differ from each other only in the presence or absence of the hydroxyl group at C 2 ... WebThe building blocks of nucleic acids are the nucleotides. A nucleotide is composed of one purine or pyrimidine base coupled to a 5-carbon sugar (pentose), D-ribose for …
Webribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds … Ribose as its 5-phosphate ester is typically produced from glucose by the pentose phosphate pathway. In at least some archaea, alternative pathways have been identified. Ribose can be synthesized chemically, but commercial production relies on fermentation of glucose. Using genetically modified strains of B. subtilis, 90 g/liter of ribose can be produced from 200 g of glucose. The conversion entails the intermediacy of gluconate and ribulose.
