Normally, the inactive T4 is converted inside the cell to the active thyroid hormone called triiodothyronine (also known as T3).
They found that cutting calories reduced two significant effects of aging, a thyroid hormone called triiodothyronine, which has been shown to help control cellular metabolism and energy balance in the body, and an inflammatory molecule called tumor necrosis factor alpha.
Iodine is required to make the thyroid's two principal products -- thyroxine (T4) and triiodothyronine (T3), generally known collectively as "thyroid hormone."
When T4 reaches target cells, it is converted to triiodothyronine (T3).
Changes in serum thyroxine, triiodothyronine, and thyrotropin induced by lithium in normal subjects and in rats (The James A. Bush memorial research awards) by Connie Child
The thyroid gland secretes two main hormones, thyroxine and triiodothyronine, into the bloodstream that stimulate all the cells in the body and control many biological processes such as growth, reproduction, development, and metabolism.
Effects of thyroxine as compared with thyroxine plus triiodothyronine in patients with hypothyroidism.
Inhibition of iodide uptake results in decreased production of iodine-rich thyroid hormones triiodothyronine, or T3 (Figure 2) and thyroxine, or T4 (Figure 3).
The thyroid gland secretes two main hormones, thyroxine and triiodothyronine, into the bloodstream.
Subclinical hyperthyroidism typically occurs when you have a low or borderline low TSH level and normal levels of triiodothyronine (T3) or thyroxine (T4).
