27 Απρ 2017 · Deoxyribose is the five-carbon sugar molecule that helps form the phosphate backbone of DNA molecules. DNA, or deoxyribonucleic acid is a polymer formed of many nucleic acids. Each nucleic acid is composed of a deoxyribose molecule bound to both a phosphate group and either a purine or a pyrimidine. Purines have two carbon and nitrogen rings ...
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.
4 Μαρ 2024 · Definition And Structure. Deoxyribose is a 5- carbon sugar found in DNA. Contains one less oxygen atom than ribose. Structure: Pentose sugar with four carbons and one hydrogen. Function In Dna. Deoxyribose forms the backbone of the DNA molecule. Key Role: Provides structural stability to DNA.
13 Σεπ 2023 · Deoxyribose: It is a five-carbon sugar molecule that forms the backbone of the DNA strands. The deoxyribose sugar molecules are connected through a phosphodiester bond, creating a sugar-phosphate backbone. Phosphate Group: It is attached to the 5’ carbon of the deoxyribose sugar.
8 Απρ 2019 · Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell.
21 Απρ 2024 · The three components of a deoxyribonucleotide are a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base, a nitrogen-containing ring structure that is responsible for complementary base pairing between nucleic acid strands (Figure \(\PageIndex{1}\)).
The Deoxyribose molecule - rotatable in 3 dimensions. Deoxyribose is a pentose (5-carbon) sugar - formula C 5 H 10 O 4. It is found in DNA. Notice the 5 carbon atoms (grey) forming the backbone of the molecule, and the oxygen atom (red) in the ring - which is a 5 sided ring, unlike glucose.
