Options
- A. T Insulin
- B. T Thyroxine
- C. Y Thyroxine
- D. Y Insulin
Answer
C. Y Thyroxine
Step-by-step solution
Thyroxine is a thyroid hormone which is an iodinated derivative of the amino acid tyrosine. The standard one-letter code for the amino acid tyrosine is Y. Insulin is a peptide hormone and not an iodinated derivative of a single amino acid. Therefore, the correct pair is Y and Thyroxine. Answer: Y Thyroxine
