a hormone produced by the thyroid gland; it regulates growth and development, organic metabolism, and the activity of the nervous system
The active form of thyroid hormone. It has three iodine atoms and is eight times more active than levothyroxine. It is the essential form used in the brain.
T3, a thyroid hormone.
Another hormone produced by the thyroid gland, more potent than thyroxine (T4). Generally produced by the breakdown of T4, sometimes a person cannot do this naturally and then must take a synthetic form of T3.
An important iodine-containing hormone secreted by the thyroid gland that assists in regulating the cellular metabolic rate of the body; much more powerful than its companion hormone thyroxine, it is considered to be the active form of thyroid hormone in tissue.
The stronger of the two key hormones produced by the thyroid gland and is produced from the conversion of T4.
hormone created by the thyroid gland. Influences most processes, like temperature, growth, heart rate.
a hormone secreted by the thyroid gland which regulates metabolism.
A hormone made by the thyroid gland. It has three iodine molecules attached to its molecular structure. It is the most powerful thyroid hormone, and affects almost every process in the body, including body temperature, growth, and heart rate. See the entire definition of Triiodothyronine
A thyroid hormone primarily converted from T4, though some excretion occurs from the thyroid directly. T3 is the metabolically active hormone.
tri-i-ode-o-THY-ro-neen A thyroid hormone that increases the rate of cellular metabolism. 669
Thyroid hormone similar to thyroxine but with one less iodine atom per molecule and produced in smaller quantity; exerts the same biological effects as thyroxine but is more potent and briefer.
The secondary hormone produced by the thyroid gland. It contains three atoms of iodine and is the metabolically active thyroid hormone.
A thyroid hormone. Also called liothyronine sodium or T-3.
thyroid hormone containing three atoms of iodine
The second hormone produced by the thyroid gland. It is more potent than thyroxine (T4). More about this.
a hormone, secreted by the thyroid gland, that regulates metabolism.
