Answer #1

DNSA regeant:

This regeant is used for estimating the reducing sugars and thus for the presence of free carbonyl group (C=O), the so-called reducing sugars. This method involves the oxidation of the aldehyde functional group (-CHO) present in, for example, glucose and the ketone functional group which are present in fructose. Simultaneously, 3,5-dinitrosalicylic acid (DNS) is reduced to 3-amino,5-nitrosalicylic acid under alkaline conditions.While using this regeanr this regeant the colour of the reagent changes from yellow to orange or red, depending upon the concentration of reducing sugar present.
