Question
Review the structure of thyroxine in Section 28.4 . Which amino acid could be biochemically altered to synthesize thyroxine? Review the amino acid structures in Chapter 18 for assistance.
Step 1
Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It is an iodine-containing compound, which means it contains iodine as well as the amino acid tyrosine. The iodine atoms are substituted at the 3, 3', 5 and 5' positions of the tyrosine Show more…

Review the structure of thyrotropin-releasing hormone (TRH) in Section 28.4 . This chemical messenger has one chiral carbon, which happens to be an alpha carbon of an amino acid. Which amino acid is part of TRH?
Look at the structure of thyroxine shown earlier in this section. Is thyroxine, an amino acid derivative, hydrophobic or hydrophilic? Explain.
Match the description to the structure for the amino acid tryptophan Neutral form of tryptophan Zwitterion structure of tryptophan Structure of tryptophan at pH = 13 Structure of tryptophan at pH = 2 NOT a possible structure of tryptophan
