Identify the correct pair having amino acid (A) and the hormone (B) that is iodinated derivative of the amino acid (A). (T and Y represent one letter code for amino acids) Amino acid (A) Hormone (B)

Options

  1. AT Insulin
  2. BT Thyroxine
  3. CY Thyroxine
  4. DY Insulin

Correct 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
