Give an example of a disaccharide that contains fructose unit in the furanose form.

Explanation

To answer the question, we need to identify a disaccharide that contains a fructose unit in the furanose form.

### Step-by-Step Solution:

1. **Understanding Disaccharides**: Disaccharides are carbohydrates formed by the condensation of two monosaccharides. They can be broken down into their constituent monosaccharides through hydrolysis.

2. **Identifying the Monosaccharides**: A disaccharide that contains a fructose unit must include fructose as one of its monosaccharide components. Fructose can exist in two forms: furanose (five-membered ring) and pyranose (six-membered ring). We are specifically interested in the furanose form.
