For this purpose, the hemiacetal includes the anomeric carbon of a monosaccharide and the alcohol role is played by a specific OH group of a second monosaccharide. How do you recognize a carbohydrate molecule? The specificity of enzymes allows one monosaccharide, glucose, to be the building block for both starch, which we think of as a major source of energy in our foods, and cellulose, which we regard as a structural material in trees and a major component of paper. Cellulose is used as a structural material to provide rigidity to plants. The reducing sugars are the carbohydrates in which the free aldehyde or free ketone group is present whereas the non-reducing sugars are those which do not contains the free aldehyde or ketone group. Besides the di- and polysaccharides we will look at later, it is very common for glucose (or other sugars) and an alcohol to form an acetal linkage.

Maltose and lactose are reducing sugars, while sucrose is a non-reducing sugar. The oxidizing agents used in carbohydrate chemistry are typically copper(II) compounds which are reduced to copper(I) oxide. The sugar type that exhibits its property as a reducing agent as it consists of free ketone and aldehyde functional groups is termed reducing sugars. Thanks for contributing an answer to Chemistry Stack Exchange! A reducing sugar has a free aldehyde (-CHO) or ketone (-C=O) group that can act as a reducing agent. This brings us to the topic of disaccharides. Of course, there are enzymes which hydrolyze the beta linkages in cellulose. Non-reducing sugars do not give a red color but remains green in color when it reacts with Benedicts solution. In the highest quartile of mono+disaccharide intake (> 142 g) weight loss was 29.9 kg compared to 25.1 kg in lowest quartile (> 72 g). It is very sensitive to even small quantities of reducing sugars (0.1%) and yields enough precipitate. While non reducing sugars does not give this test. All monosaccharides are reducing sugars. (Honours) Part-III Practical, Pharmacology II,MANIK. Research Institute, The reducing sugar reduces the copper (III) ions in these tests into copper (I) ions resulting in the formation of a brick-red copper oxide precipitate.
