Monoiodotyrosine is a precursor of thyroid hormone and results from iodization of tyrosine at the meta- position of the phenol ring.
Two units can combine to form 3,3'-diiodothyronine. One unit can combine with diiodotyrosine to form triiodothyronine, as occurs in the colloid of the thyroid follicle.
It is abbreviated "MIT".[1]

- Reductive dehalogenation is not typical of aerobic organisms but plays a significant role in iodide homeostasis and thyroid activity. The flavoprotein iodotyrosine deiodinase (IYD) is responsible for iodide salvage by reductive deiodination of the iodotyrosine derivatives formed as byproducts of thy
