WebApr 4, 2024 · It consists of adenine, ribose, and a triphosphate moiety. Adenosine is attached by the 9-nitrogen atom to the 1-carbon atom of ribose which in turn is attached at the 5-carbon atom of sugar to a triphosphate group. Three phosphate groups form a triphosphate moiety. They are termed alpha (α), beta (β), and gamma (γ) phosphate groups. WebThe phosphate group of one nucleotide bonds covalently with the sugar molecule of the next nucleotide, and so on, forming a long polymer of nucleotide monomers. The sugar–phosphate groups line up in a “backbone” for each single strand of DNA, and the nucleotide bases stick out from this backbone.

Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.

WebThe phosphate backbone is a chemical hallmark of contemporary nucleic acids. The importance of phosphate stems from the fact that phosphate provides many favorable electrostatic properties and significant hydrolytic stability. WebRibose 5-phosphate ( R5P) is both a product and an intermediate of the pentose phosphate pathway. The last step of the oxidative reactions in the pentose phosphate pathway is the production of ribulose 5-phosphate. Depending on the body's state, ribulose 5-phosphate can reversibly isomerize to ribose 5-phosphate.

WebJan 24, 2024 · A Phosphate Group Nitrogenous bases include purine molecules (adenine and guanine) and pyrimidine molecules (cytosine, thymine, and uracil.) In DNA, the five-carbon sugar is deoxyribose, while ribose is the pentose sugar in RNA. Nucleotides are linked together to form polynucleotide chains.

WebApr 13, 2024 · A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
