Tyrosine is first iodized to monoiodotyrosine and then to diiodotyrosine. Then, more and more of the iodotyrosine residues become coupled with one another

The major hormonal product of the coupling reaction is the molecule thyroxine (T4), which is formed when two molecules of DIT are joined together; the thyroxine then remains part of the thyroglobulin molecule.
