What is essentially the difference bewteen α-glucose and β-glucose ? What is meant by pyranose structure of glucose ?      (3 marks)

The two cyclic hemiacetal forms of glucose differ only in the configuration of the hydroxyl group on the first carbon atom called anomeric carbon. Such isomers i.e. α-form and β-form are called anomers. α-glucose is the monomer unit of strach and β-glucose is the monomer unit of cellulose. The six membered cyclic structure of glucose is called pyranose structure.

Pyranose structure of glucose : The six membered ring containing 5 carbon atoms and one oxygen atom because of its resemblance with pyron is called the pyranose form.
