The iodine subsequently oxidized by peroxidase enzymes, which itself is activated by TSH. Thyroid Peroxidase first generates I2 by oxidizing I- ions present in the follicular lumen.

Iodide that enters the thyroid remains in the free state only briefly before it is further metabolized and bound to tyrosyl residues in Tg. An active transport for iodide in the gastric mucosa has an obvious value because it provides iodine to the circulation for use in the thyroid.

The colloid droplets then deliver their content to lysosomes. It undergoes core glycosylation and then monomers fold into stable dimers. In healthy subjects the entire procedures of T4 and T3 synthesis re-start again following a drop in serum T4 and T3 concentration. Effect of Thyroid Hormones on Metabolism The main activity of the thyroid hormones T3 and T4 is to boost the basal metabolic rates of proteins, fats, and carbohydrates as well as vitamins. One would expect to find i control systems preventing excess hormone production that would result from the processing of excessive amounts of prohormonal Tg molecules and ii checking systems avoiding the use of Tg molecules with no or a low hormone content.

Zulkitaxe

Exposure of Tg to reducing agents yields an N-terminal peptide of about kDa, depending on the animal species, that contains the major hormonogenic site of Tg One scheme proposes that oxidation produces free radicals of iodine and tyrosine, while both are bound to TPO to form MIT which then separates from the enzyme Fig. Lumenal Tg molecules, either free or associated to membrane proteins acting as Tg receptors, enter the pits and are then sequestrated into the newly-formed vesicles

Learning Objectives List the actions of thyroid hormones Key Takeaways T4 is converted to T3 by peripheral organs such as the liver, kidney, and spleen. It is noteworthy that this hypothyroid status was limited to the neonatal period, when thyroid hormone requirement is the highest, and was not detectable in adulthood since adult heterozygotes in these families presented normal TSH serum levels.
