Invert sugar is mixture of (JIPMER 2019)

A.D-glucose + D-fructose✓ Correct

B.L-glucose + D-fructose

C.L-glucose + D-glucose

D.L-glucose + L-glucose

Explanation

Invert sugar is a mixture of D-glucose and D- fructose. Solution of sucrose is dextrorotatory. When sucrose is hydrolysed it forms equimolar quantity of D-glucose and D-fructose. The solution of formed products is found to be laevoratatory. This change in optical properties of sucrose is called inversion of cane sugar. The equimolar product formed. i.e., D- gluccose and D-fructose is called inver sugar.
