Explanation:
This is a trace element needed for the synthesis of the two thyroid hormone ; T4- thyroxine and T3-triiodothyronine. Four iodine molecules are added in T4 synthesis, and three for T3 synthesis. Generally T4 is the major hormone produced, but biologically transformed into active form T3.
