Triiodothyronine

 

(3,5,3’-triiodothyronine), an animal and human hormone formed in the follicles of the thyroid gland by the oxidative condensation of monoiodotyrosine and diiodotyro-sine.

Like the other thyroid hormone, thyroxine, triiodothyronine has a multiple, varied effect on the organism and on the organism’s growth, differentiation, and metabolism. It is secreted into the blood in significantly smaller amounts than thyroxine, but its effect on metabolism is more rapid, since it is less strongly bound to specific plasma proteins and thus enters the tissue fluid and cells more easily.
