Question

85)The The sugar that yields only glucose on hydrolysis
a) Maltose
b) Lactose
c)Fructose
d) None of the above​

Answer 1

The sugar that yields only glucose on hydrolysis is (a) Maltose

Reason :

Maltose is a type of Disaccharide. It contains two units of glucose as pyranose of which one is reducing and the other is non-reducing in nature. The C-1 of non-reducing glucose is linked to the C-4 of reducing glucose by Glycosidic Linkage.

1 mole of maltose, on hydrolysis, produces 2 mole of D-Glucose.

        Maltose ---------> Glucose + Glucose
