Proteins are the polymer of

Options

A. Fatty acid
B. Nucleic acid
C. Amino acid
D. Citric acid

Explanation

**Step-by-Step Solution:**

1. **Understanding the Definition of Proteins**:
- Proteins are large, complex molecules that play many critical roles in the body. They are essential for the structure, function, and regulation of the body’s tissues and organs.

2. **Identifying the Building Blocks of Proteins**:
- The basic units that make up proteins are called amino acids. There are 20 different amino acids that combine in various ways to form proteins.

3. **Understanding Polymerization**:
- A polymer is a large molecule made up of repeating structural units (monomers). In the case of proteins, the monomers are amino acids.

4. **Formation of Proteins**:
- Amino acids are linked together by peptide bonds through a process called translation, which occurs in the ribosomes of cells. This process involves the assembly of amino acids in a specific sequence dictated by the genetic code.

5. **Conclusion**:
- Therefore, proteins are polymers of amino acids.

**Final Answer**: Proteins are the polymer of amino acids.
