The pentose sugar in dna is ribose
Webb-The pentose sugar in DNA is ribose. -Hydrogen bonds formed between the sugar‑phosphate backbones of the two DNA chains help to stabilize DNA structure. … WebbPentose sugar in the nucleotide of DNA is deoxyribose whereas in the nucleotide of RNA it is ribose. Both deoxyribose and ribose are five-membered ring-shaped molecules with carbon atoms and a single oxygen atom, with side groups attached to the carbons.

In chemistry, a pentose is a monosaccharide (simple sugar) with five carbon atoms. The chemical formula of many pentoses is C 5H 10O 5, and their molecular weight is 150.13 g/mol. Pentoses are very important in biochemistry. Ribose is a constituent of RNA, and the related molecule, deoxyribose, is a constituent of … Visa mer The aldopentoses are a subclass of the pentoses which, in the linear form, have the carbonyl at carbon 1, forming an aldehyde derivative with structure H–C(=O)–(CHOH)4–H. The most important example is Visa mer In the cell, pentoses have a higher metabolic stability than hexoses. A polymer composed of pentose sugars is called a Visa mer The closed or cyclic form of a pentose is created when the carbonyl group interacts with a hydroxyl in another carbon, turning the carbonyl into a hydroxyl and creating an ether bridge –O– between the two carbons. This intramolecular reaction yields a Visa mer WebbTerms in this set (34) 1. Describe the structure of a nucleotide. The nucleotide is the repeating structural unit of both DNA and RNA. A nucleotide has three components: at …
WebbThe pentose sugar in the structural moiety of the polynucleotide chain can be either deoxyribose or ribose sugar. Both deoxyribose and ribose sugars are the five-carbon monosaccharides or pentoses, which occur in the DNA and RNA, respectively. The structural difference between deoxyribose and ribose sugar is due to the deficiency of … WebbThe sugar bonds to a purine or pyrimidine base at the. Question: Question Identify the incorrect statement. Select the correct answer below: The pentose sugar in DNA is deoxyribose. In RNA the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the second carbon of the ribose and hydrogen on the second ...

[2] Pentoses are very important in biochemistry. Ribose is a constituent of RNA, and the related molecule, deoxyribose, is a constituent of DNA.
WebbDeoxyribose, 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.Discovered in 1929 by Phoebus Levene, deoxyribose is most notable for its presence in DNA.Since the pentose sugars …
