WebMay 6, 2024 · The thyroid hormones Thyroxine (T4) and Triiodothyronine (T3) are produced and secreted by the thyroid gland. Each molecule of T4 and T3 is made up of a protein and iodine (in the form of iodide). T4 contains 4 molecules of iodide and T3 contains 3 molecules of iodide – hence the names T4 and T3. This is what T4 (Thyroxine) looks like. WebTSH interacts with specific cell receptors on the thyroid cell surface and gives rise to 2 main actions.
