Sucrose is a

Options

A. monosaccharide
B. Disaccharide
C. polysaccharide
D. mixture of glucose and fructose

Explanation

**Step-by-Step Solution:**

1. **Understanding Sucrose**: Sucrose is a type of sugar that is commonly found in plants. It is important to identify its classification among carbohydrates.

2. **Identifying the Options**: The options provided are:
- Monosaccharides
- Disaccharides
- Polysaccharides
- Mixture of glucose and fructose

3. **Analyzing the Composition of Sucrose**: Sucrose is composed of two simpler sugars (monosaccharides), specifically glucose and fructose. This indicates that it is not a monosaccharide (which consists of a single sugar unit) and also not a polysaccharide (which consists of many sugar units).

4. **Determining the Type of Sugar**: Since sucrose is made up of two monosaccharides, it is classified as a disaccharide. Disaccharides are sugars formed from two monosaccharide units.

5. **Hydrolysis of Sucrose**: When sucrose undergoes hydrolysis, it breaks down into its constituent monosaccharides, glucose and fructose. This further confirms its classification as a disaccharide.

6. **Identifying the Nature of Sucrose**: Sucrose is also known as a non-reducing sugar because it does not have a free aldehyde or ketone group that can participate in redox reactions.

7. **Conclusion**: Based on the analysis, the correct classification of sucrose is that it is a disaccharide.

**Final Answer**: Sucrose is a disaccharide.
