Triiodothyronine hormone structure Stock Photo by sciencepics 121653622 The physiological activity of thyroid hormone is regulated by a system of enzymes that activate, inactivate or simply discard the prohormone T 4 and in turn functionally modify T 3 and rT 3. Triiodothyronine maintains cardiac transverse-tubule structure and function Highlights Thyroid hormone deficient hearts have disorganized T-tubules, impaired EC coupling Thyroid deficiency causes decreased rates of Ca 2+ release/re-uptake, reduced contractility STORM imaging shows reduced RyR2 cluster number and size in T3-deficient myocytes Also known as T3 and liothyronine. Triiodothyronine: A hormone that is made by the thyroid gland. The other major thyroid hormone is called thyroxine (T4), which contains 4 atoms of iodine and together they help control the rate at which the body uses energy. Most triiodothyronine in our blood exists as a bound form with proteins. Cellular Structure. Triiodothyronine (referred to as T3 due to having 3 molecules of iodine attached to its molecular structure) makes up about 20% of all the hormones made by the thyroid, and is the most powerful even though it only has a lifespan of about 2 days.
