Non-reducing sugar is a type of sugar that doesnt have a free aldehyde or ketone group, as a result of which the sugar cannot act as a reducing agent. First, it is catalyzed by the enzyme maltase. Since our glycosidases are unable to hydrolyze the beta linkages in cellulose, we cannot digest cellulose, even though it is also a polymer of glucose. test for reducing sugars sciencing april 17th, 2019 - once added to the test solution reducing sugars reduce the blue copper sulphate from the benedict s solution to a red brown copper sulphide which is seen as the precipitate and is responsible for the color change non reducing sugars cannot do this this particular test only provides Number of Views: 3435.
Why are polysaccharides non-reducing sugars? A disaccharide can be a reducing sugar or a non-reducing sugar. This suggests that the enzyme holds the two molecules of glucose in specific positions so that only the OH on carbon 4 of one glucose can reach the anomeric carbon of the other glucose. What are five examples of non-reducing sugars? In this case, that specificity shows up in the fact that the new acetal linkage has the alpha configuration, not the beta (and correspondingly, maltase catalyzes the hydrolysis of an alpha linkage but does nothing to the beta linkage). This is because it contains a free ketone group. Fehling's test is one of the most common tests used for the identification of reducing and non - reducing sugars.
