What is the difference between `alpha` - glucose and`beta`- glucose ? Write their cyclic structures

Explanation

Cyclic structure of glucose : Glucose exists in two cyclic fonns, These two cyclic fonns are in equilibrium with open chain structure as shown below :

These two structures differ only by configuration of `C_1`. This carbon is known as anomeric carbon.
The six membered cyclic structure of glucose is called pyranose structure. The five membered. cyclic structure of glucose is called furanose structure,
