Thyroid Stimulating Hormone (TSH): This hormone is secreted from TSH cells of adenohypophysis. It is a glycoprotein hormone. Its molecular weight is about 30 KD. TSH (with a half-life of about an hour) stimulates the thyroid gland to secrete the hormone thyroxine (T4), which has only a slight effect on metabolism. T4 is converted to triiodothyronine (T3), which is the active hormone that stimulates metabolism. About 80% of this conversion is in the liver and other organs, and 20% in the thyroid itself.
