Invert sugar is mixture of
Options
- AD-glucose + D-fructose
- BL-glucose +D -fructose
- CL-glucose + D-glucose
- DL-glucose + L-glucose
Correct answer
A. D-glucose + D-fructose
Step-by-step solution
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 laevorotatory. This change in optical properties of sucrose is called inversion of cane sugar. The equimolar product formed, i.e D-glucose and D-fructose is called invert sugar.
