Description

T3

Triiodothyronine, also known as T₃, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. Production of T₃ and its prohormone thyroxine (T₄) is activated by thyroid-stimulating hormone (TSH), which is released from the anterior pituitary gland. This pathway is part of a closed-loop feedback process: Elevated concentrations of T₃, and T₄ in the blood plasma inhibit the production of TSH in the anterior pituitary gland. As concentrations of these hormones decrease, the anterior pituitary gland increases production of TSH, and by these processes, a feedback control system stabilizes the level of thyroid hormones in the bloodstream.

T₃ is the true hormone. Its effects on target tissues are roughly four times more potent than those of T₄. Of the thyroid hormone that is produced, just about 20% is T₃, whereas 80% is produced as T₄. Roughly 85% of the circulating T₃ is later formed in the liver and anterior pituitary by removal of the iodine atom from the carbon atom number five of the outer ring of T₄.
