why is the sugar of dna called deoxyribose
Deoxyribose
Deoxyribose , or more precisely 2 - deoxyribose , is a monosaccharide with idealized formula H − ( C = O ) − ( CH ) − ( CHOH ) − H. Its name indicates that it is a deoxy sugar , meaning that it is derived from the sugar ribose by loss of an oxygen atom . Since the pentose sugars arabinose and ribose only differ by the stereochemistry at C2 ′ , 2 - deoxyribose and 2 - deoxyarabinose are equivalent , although the latter term is rarely used because ribose , not arabinose , is the precursor to deoxyribose .

The name deoxyribose is because it is a deoxy sugar, which means that it is derived from the sugar ribose by loss of an oxygen atom.
