Reducing vs Non reducing sugars ✔️✔️

Sugars are Carbohydrates. On the basis of chemical nature they are differentiated into Reducing sugars & Non reducing sugars,

✔️What are the differences between them?

It is a very common question among Chemistry & Biochemistry students. 

For Detail explanation with molecular structures please check the following:
