The enzyme TPO is responsible for iodination of tyrosine and coupling them to form TThe most primitive thyroid condition in vertebrates is considered to be that found in the adult cyclostomes in which only scattered follicles may be present.
However, extracellular storage of thyroid hormones does not occur in the cyclostome follicle, and iodoproteins are retained in the follicular cells of these primitive fishes.
However, iodine in the diet may combine with different components and exist as organic iodine, which may have a low uptake in the digestive tract.
The retention of these glycoproteins, the ability to accumulate iodide, and the formation of iodinated thyronines were acquired by certain cells of the endostyle ().Exclamations are short utterances that you make when you are very surprised or upset.
