Deoxyribose, 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, [4] deoxyribose is most notable for its presence in DNA.
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.
l-Deoxyribose is an organic compound with formula C 5 H 10 O 4. It is a synthetic monosaccharide, a stereoisomer (mirror image) of the natural compound d-deoxyribose. l-Deoxyribose can be synthesized from d-galactose. [3] It has been used in chemical research, e.g. in the synthesis of mirror-image DNA. [4]
Ribose Zippers: View of a canonical ribose zipper between two RNA backbones. [33] The ribose zipper is an RNA tertiary structural element in which two RNA chains are held together by hydrogen bonding interactions involving the 2’OH of ribose sugars on different strands. The 2'OH can behave as both hydrogen bond donor and acceptor, which ...
5-carbon sugar which is called deoxyribose (found in DNA) and ribose (found in RNA). One or more phosphate groups. [1] The nitrogen bases adenine and guanine are purine in structure and form a glycosidic bond between their 9 nitrogen and the 1' -OH group of the deoxyribose.
The win makes Florida 5-5 with a home game vs. No. 11 Ole Miss in Week 13 and a road trip to a 1-9 Florida State team in the regular season finale. Given how terrible Florida State has been, the ...
Florida State, no matter how stung by a College Football Playoff committee that made a sham of the system, has something to play for against Georgia. Florida State still could claim to be No. 1 ...
The chemical structure of DNA is insufficient to understand the complexity of the 3D structures of DNA. In contrast, animated molecular models allow one to visually explore the three-dimensional (3D) structure of DNA. The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as ...
