WebIn RNA, the carbon at the C-2 position is attached to a hydroxyl (OH) group. In DNA, the carbon at the C-2 does not contain this hydroxyl group; rather it is replaced by a hydrogen (H) atom. Therefore, the pentose ring in DNA is considered a deoxyribose (it is a deoxygenated five-carbon sugar ring). WebRibose is a monosaccharide having five carbons, thus called a pentose sugar. Ribose is the most important pentose present in living organisms. It is an aldose sugar, having an aldehydic functional group.
