Which of the following cannot be used to distinguish between glucose and fructose?

Which is a reducing sugar?

What is the phenomenon of rapid interconversion of $\alpha-D-$glucose into $\beta-D-$glucose in solution called?

Glycogen is a branched chain polymer of $\alpha-D$-glucose units in which the chain is formed by $C_1-C_4$ glycosidic linkage,whereas branching occurs by the formation of $C_1-C_6$ glycosidic linkage. The structure of glycogen is similar to:

Write the reactions of $D-Glucose$ which cannot be explained by its open-chain structure. How can the cyclic structure of glucose explain these reactions?

The incorrect statement about $Glucose$ is :
