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 . </P> <P> Deoxyribose was discovered in 1929 by Phoebus Levene . </P>
