Invert sugar is mixture of

  • Correct answer
    A
    D-glucose + D-fructose
  • B
    L-glucose +D -fructose
  • C
    L-glucose + D-glucose
  • D
    L-glucose + L-glucose

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.

Hence, the correct answer is option: 'A'.
