Amino acids like methionine and cysteine contain

Options

A. Zn
B. S
C. B
D. Cl

Answer

**Step-by-Step Solution:**

1. **Understanding Amino Acids**: Amino acids are organic compounds that serve as the building blocks of proteins. They contain two key functional groups: an amino group (-NH2) and a carboxyl group (-COOH).

2. **Identifying Key Elements**: The primary elements found in amino acids include carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). However, some amino acids also contain other elements that are crucial for their structure and function.

3. **Focusing on Methionine and Cysteine**: Methionine and cysteine are two specific amino acids. Methionine is known for containing a sulfur atom in its structure, while cysteine also contains sulfur and is important for forming disulfide bonds that stabilize protein structures.

4. **Analyzing the Options**: The question provides four options:
- Zinc
- Sulfur
- Boron
- Chlorine

5. **Identifying the Correct Answer**: Since both methionine and cysteine contain sulfur in their molecular structure, the correct answer to the question is **sulfur**.

6. **Conclusion**: Therefore, the answer to the question "Amino acids like methionine and cysteine contain" is **sulfur**.
