Glycosidic linkage is present in

Options

A. (1) Proteins
B. (2) Lipids
C. (3) Carbohydrates
D. (4) Nucleic acids

Answer

To determine where glycosidic linkages are present, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Glycosidic Linkage**:
- Glycosidic linkage is a type of covalent bond that connects carbohydrates. It specifically links one monosaccharide to another.

2. **Identifying Carbohydrates**:
- Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They include monosaccharides (simple sugars), disaccharides (two monosaccharides linked together), and polysaccharides (long chains of monosaccharides).

3. **Examples of Glycosidic Linkages**:
- Common examples include sucrose, which is formed by the glycosidic linkage between glucose and fructose. This bond allows these two monosaccharides to form a disaccharide.

4. **Conclusion**:
- Since glycosidic linkages are specifically found in carbohydrates, the correct answer to the question is that glycosidic linkages are present in carbohydrates.

### Final Answer:
Glycosidic linkage is present in carbohydrates.
