Which of the following biomolecules are called target molecules or drugs target?

Options

A. Nucleic acids
B. Proteins
C. Carbohydrates
D. All of these

Explanation

To answer the question "Which of the following biomolecules are called target molecules or drug targets?", we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Drug Targets**:
- A drug target is defined as a biomolecule that interacts with a drug. This interaction can lead to a therapeutic effect, which is the desired outcome of drug administration.

2. **Identifying the Biomolecules**:
- The options provided are:
- Proteins
- Nucleic Acids
- Carbohydrates

3. **Analyzing Each Option**:
- **Proteins**: Many drugs are designed to interact with specific proteins in the body. These proteins can be enzymes, receptors, or other functional proteins that play a crucial role in biological processes.
- **Nucleic Acids**: Drugs can also target nucleic acids (DNA and RNA). For example, some anticancer drugs and antiviral drugs work by interacting with the genetic material of cells.
- **Carbohydrates**: While carbohydrates can be involved in drug interactions (such as in glycoproteins), they are less commonly the primary target for drug action compared to proteins and nucleic acids.

4. **Conclusion**:
- All three biomolecules (proteins, nucleic acids, and carbohydrates) can serve as drug targets. Therefore, the correct answer is that all of these biomolecules are considered drug targets.

### Final Answer:
All of the above (Proteins, Nucleic Acids, and Carbohydrates) are called target molecules or drug targets.
