The individual monosaccharides are linked in a polysaccharide :-

Options

A. By peptide bond
B. By glycosidic bond
C. By ester bond
D. By hydrogen bond

Answer

To answer the question about how individual monosaccharides are linked in a polysaccharide, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Polysaccharides**:
- Polysaccharides are large molecules made up of many monosaccharide units (simple sugars) linked together.

2. **Identifying the Bonds**:
- There are different types of bonds that can link molecules together, including peptide bonds, glycosidic bonds, ester bonds, and hydrogen bonds.

3. **Defining Glycosidic Bonds**:
- The specific type of bond that links monosaccharides in a polysaccharide is called a glycosidic bond. This bond forms when the hydroxyl group of one monosaccharide reacts with the hydroxyl group of another, releasing a molecule of water (a dehydration reaction).

4. **Examples of Polysaccharides**:
- Common examples of polysaccharides include starch, glycogen, and cellulose. These are all formed by the glycosidic linkage of multiple monosaccharide units.

5. **Conclusion**:
- Therefore, the correct answer to the question is that individual monosaccharides are linked in a polysaccharide by glycosidic bonds.

### Final Answer:
The individual monosaccharides are linked in a polysaccharide by **glycosidic bonds**.
