Yeah I read a lot about Iodine, and everything says its primary use is to make the thyroid hormones which are ostensibly signaling molecules. I think those "hormones" are actually just a storage site for Iodine. The hormones are T1, T2, T3, and T4 and differ mainly by the number of Iodine atoms attached. That just doesnt look like signaling to me. Its storage for an important atom that would diffuse and leave the body if not incorporated into an organic molecule.
