The name "ribose" is used in biochemistry and biology to refer to all of these forms, though more specific names for each are used when required. Deoxyribose versus Ribose sugars. Several isomers exist with the formula H−(C=O)−(CH2)−(CHOH)3−H, but in deoxyribose all the hydroxyl groups are on the same side in the Fischer projection. A sugar derived from ribose by replacement of a hydroxyl group by hydrogen. Nucleic Acid Synthesis/Breakdown . See more. Guanine.
