What are glucosidic linkages? In which type of biomolecules are they present?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Glycosidic Linkage**:
- A glycosidic linkage is a type of covalent bond that connects two monosaccharide molecules. This bond is formed when the hydroxyl group (-OH) of one monosaccharide reacts with the hydroxyl group of another monosaccharide, resulting in the release of a water molecule (H₂O). This process is known as a condensation reaction.

2. **Formation of Glycosidic Linkage**:
- During the formation of a glycosidic linkage, the -OH group from one monosaccharide and a hydrogen atom (H) from another monosaccharide are removed, leading to the release of a water molecule. The remaining oxygen atom forms a bridge between the two monosaccharides, creating the glycosidic bond.
