Invert sugar, is
Correct Answer: equimolar mixture of glucose and fructose
Description: Hydrolysis of sucrose (optical rotation +66.5°) will produce one molecule of glucose (+52.5°) and one molecule of fructose (–92°).
Therefore, the products will change the dextrorotation to levorotation, or the plane of rotation is inverted. Equimolecular mixture of glucose and fructose thus formed is called invert sugar. The enzyme producing hydrolysis of sucrose is called sucrase or invertase.
Honey contains invert sugar. Invert sugar is sweeter than sucrose.
