In polysaccharide the individual monosaccharides are linked by a bond. This bond is formed by dehydration. The bond is -

Options

A. Ester bond
B. Glycosidic bond
C. H-bond
D. lonic bond

Answer

**Step-by-Step Solution:**

1. **Understanding Polysaccharides**: Polysaccharides are complex carbohydrates made up of long chains of monosaccharides (simple sugars) linked together.

2. **Identifying the Type of Bond**: In polysaccharides, the individual monosaccharides are connected through specific types of bonds.

3. **Dehydration Reaction**: The process of linking monosaccharides involves a dehydration reaction, also known as a condensation reaction. This reaction occurs when two monosaccharides combine, resulting in the release of a water molecule.

4. **Types of Bonds**: There are different types of bonds that can occur in biomolecules:
- **Ionic Bonds**: These are formed between positively and negatively charged ions.
- **Hydrogen Bonds**: These occur between polar molecules, such as between nitrogenous bases in DNA.
- **Ester Bonds**: These are found in lipids and connect fatty acids to glycerol.

5. **Identifying the Correct Bond**: The bond that specifically links monosaccharides in polysaccharides is known as a glycosidic bond. This bond is formed during the dehydration reaction when a water molecule is released.

6. **Conclusion**: Therefore, in polysaccharides, the individual monosaccharides are linked by a glycosidic bond, which is formed through dehydration.

**Final Answer**: The bond is a glycosidic bond.
