Question: are deoxyribose and ribose isomers?
Answer: Deoxyribose is a deoxy sugar, which is derived from ribose by the loss of an oxygen atom. This is the reason the number of oxygen atoms in deoxyribose is one less than that in ribose. ... 2-Deoxyribose, on the other hand, has two enantiomers (stereoisomers that are identical but non-superposable).
