How is diiodotyrosine formed?

Diiodotyrosine, 3,5-diiodotyrosine (25.2.1), is Direct iodination of tyrosine with iodine in the presence of sodium iodide in aqueous ethylamineOr add hydrogen peroxide to a mixture of acetic acid and hydrochloric acid [10–12]. Diiodotyrosine has no significant hormonal activity.

Which molecule binds together to form T3?

Two DIT molecules combine to form thyroxine (T4).Triiodothyronine (T3) is produced by MIT and DIT And through the single deiodination of T4 in the periphery.
