Follicular cells synthesize '''Thyroglobulin''' in their golgi apparatus. This is a glycoprotein consisting of 70 linked tyrosine molecules, 10% of which are ''iodinated'', and is stored in the colloid.
Follicular cells synthesize '''Thyroglobulin''' in their golgi apparatus. This is a glycoprotein consisting of 70 linked tyrosine molecules, 10% of which are ''iodinated'', and is stored in the colloid.
The thyroglobulin is then split to form the two amino acid derivative [[Hormones - Anatomy & Physiology|hormones]] produced in the thyroid gland:
The thyroglobulin is then split to form the two amino acid derivative [[Hormones - Anatomy & Physiology|hormones]] produced in the thyroid gland which are Triiodothyronine (T3) and Thyroxine (T4).
Thyroxine contains 4 iodine atoms, triiodothyronine contains 3. Creation of these two [[Hormones - Anatomy & Physiology|hormones]] is the only role of iodine in the body.
