T3 singular

Etymology

The word T3 comes from the full name triiodothyronine, where tri- means 'three', iodine is the chemical element added, and thyroid is the gland that makes it. So T3 is the thyroid hormone with three iodine atoms, and that small difference helps explain why it acts differently from T4.
