Correct answer
CY Thyroxine
Step-by-step explanation
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
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
