Invert sugar is mixture of

Options

A. a type of cane sugar
B. optically inactive form of sugar
C. mixture of glucose and galactose
D. mixture of glucose and fructose in equimolar quantities

Answer

To solve the question regarding what invert sugar is a mixture of, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Invert Sugar**:
Invert sugar is a type of sugar that is formed by the hydrolysis of sucrose. This process involves breaking down sucrose into its constituent monosaccharides.

2. **Formation of Invert Sugar**:
When sucrose (which is a disaccharide composed of glucose and fructose) is heated with water in the presence of an acid or enzyme, it undergoes hydrolysis. This results in the formation of two monosaccharides: glucose and fructose.

3. **Composition of Invert Sugar**:
The resulting invert sugar is essentially a mixture of glucose and fructose in equimolar quantities. This means that the amounts of glucose and fructose are equal in the mixture.

4. **Identifying the Correct Option**:
Given the options in the question, we need to identify which one correctly describes invert sugar. The correct option states that invert sugar is a mixture of glucose and fructose in equimolar quantities.

5. **Conclusion**:
Therefore, the answer to the question is that invert sugar is a mixture of glucose and fructose.

### Final Answer:
Invert sugar is a mixture of glucose and fructose in equimolar quantities.
