Chemically, Deoxyribose (or 2-deoxyribose) is a single-ring 5-carbon (pentose) monosaccharide sugar. It is a derivative of ribose. Loss of oxygen atom on the 2’ carbon in ribose results in the formation of Deoxyribose.
Together with nitrogenous base and phosphate, it forms nucleotides, the monomeric unit of deoxyribonucleic acid (DNA).
Deoxyribose forms deoxyribonucleoside when a nitrogenous base joins deoxyribose sugar by replacing hydrogen of 1’ carbon. Deoxyribonucleoside forms deoxyribonucleotide when phosphate replaces hydrogen of 5’ carbon of deoxyribose. Deoxyribonucleotides when joined together by replacing hydrogen of deoxyribose 3’ carbon though phosphate oxygen, polymeric DNA molecule is formed.
