Question

Quizplus · Accepted Answer

The synthesis of T3 and T4 requires tyrosine, a key amino acid involved in the production of thyroid hormone, and the trace mineral iodine.Two additional molecules of iodine bind to the tyrosyl ring in a reaction that involves thyroid peroxidase (TPO), an enzyme.When T4 is released from the thyroid, it is primarily in a bound form with thyroid-binding globulin (TBG), a protein that transports thyroid hormones through the bloodstream but is not required for production.
