What is essentially the difference between α-form of glucose and β-form of glucose? Explain.

α-form of glucose and β-form of glucose differ only in the configuration of the hydroxyl group at C1 in cyclic structure of glucose/hemiacetal form of glucose/ pyranose structure of glucose.


In α -form of glucose OH group lies at C1 towards right but in β -form of glucose it is towards left. This is because OH group at Cl in glucose is chiral.
