Iodination of proteins
WebIodination [I2] Iodination Definition: Iodination is a reaction where iodine is added to a double bond of alkene to give a diiodide. Iodination Explained: Alkene chlorination and bromination are very general reactions, and mechanistic study of these reactions provides additional insight into electrophilic addition reactions of alkenes. Much less detail is … Web23 nov. 2015 · Synthesis of T4, the primary form of TH released by the thyroid gland, consists of two sequential steps: iodination of selected tyrosines of thyroglobulin (Tg; a large glycoprotein), and coupling of two doubly iodinated tyrosines within Tg to produce T4. Thus, TH synthesis relies on iodide availability.
