Albinism is a result of inability of the system to convert amino acid

Options

A. Alanine
B. Tryptophan
C. Lysine
D. Tyrosine

Answer

**Step-by-Step Solution:**

1. **Understanding Albinism**: Albinism is a genetic disorder characterized by a partial or complete absence of melanin, the pigment responsible for coloration in skin, hair, and eyes.

2. **Identifying the Cause**: The primary cause of albinism is the deficiency or lack of a specific enzyme that is crucial for the production of melanin. This enzyme is known as tyrosine 3-monooxygenase.

3. **Role of Tyrosine**: Melanin is synthesized from the amino acid tyrosine. In individuals with albinism, the defective gene leads to the absence of tyrosine 3-monooxygenase, which means that tyrosine cannot be converted into melanin.

4. **Analyzing the Options**: The question provides four amino acids: alanine, tryptophan, lysine, and tyrosine. We need to identify which amino acid is involved in the production of melanin.

5. **Conclusion**: Since melanin is produced from tyrosine, the inability to convert tyrosine into melanin due to the lack of the enzyme leads to albinism. Therefore, the correct answer is tyrosine.

**Final Answer**: Tyrosine
