<P> A carbohydrate is a biomolecule consisting of carbon ( C ) , hydrogen ( H ) and oxygen ( O ) atoms , usually with a hydrogen -- oxygen atom ratio of 2 : 1 ( as in water ) ; in other words , with the empirical formula C ( H O ) ( where m may be different from n ) . This formula holds true for monosaccharides . Some exceptions exist ; for example , deoxyribose , a sugar component of DNA , has the empirical formula C H O . The carbohydrates are technically hydrates of carbon ; structurally it is more accurate to view them as aldoses and ketoses . </P>
