A deoxyribonucleotide of DNA is formed by cross- linking of three chemicals—phosphoric acid (H3PO4), deoxyribose sugar (C 5 H 10 O 4) and a nitrogen base. The basic component of biological nucleic acids is the nucleotide, each of which contains a pentose sugar (ribose or deoxyribose), a phosphate group, and a nucleobase. Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H−(C=O)−(CH 2)−(CHOH) 3 −H. Ribose forms a five member ring composed of four carbon atoms and one oxygen. Synonyms: C5H10O4 [chemical formula]. In aqueous solution, deoxyribose primarily exists as a mixture of three structures: the linear form H−(C=O)−(CH2)−(CHOH)3−H and two ring forms, deoxyribofuranose ("C3′-endo"), with a five-membered ring, and deoxyribopyranose ("C2′-endo"), with a six-membered ring. The enzyme can then transfer deoxyribose 1-phosphate to other nitrogenous bases.
