Introduction

1.Despite having the aldehyde group, glucose does not give Schiff’s test (test for detecting aldehyde group) 2.It does not form the hydrogen sulphite addition product with NaHSO3. 3.Glucose has two crystalline forms which are named as ? and ?. 4.The two cyclic hemi acetal forms of glucose differ only in the configuration of the hydroxyl group at C1, called anomeric carbon. Such isomers, i.e., ?-form and ?-form, are called anomers. 5.The six membered cyclic structure of glucose is called pyranose structure (?– or ?–). 6. Pyran is a cyclic organic compound with one oxygen atom and five carbon atoms in the ring.
