the products formed are Monoiodotyrosine (MIT) and Diiodotyrosine (DIT)
Explanation:
Monoiodotyrosine (MIT) is a precursor of thyroid hormone and results from iodization of tyrosine at the meta- position of the phenol ring, and Diiodotyrosine (DIT) is a precursor in the production of thyroid hormone, and results from iodization of monoiodotyrosine at the other meta- position on the phenol ring.
Once inside the gland, the iodide is oxidized by a peroxidase to iodine and then bound to tyrosine, forming either monoiodotyrosine or diiodotyrosine. Both of these are then coupled enzymatically to form T4 or T3. The T3 and T4 are bound to the protein thyroglobulin and stored as colloid in the gland.
Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.
The mass of the reactants should not change, in fact it would be equal because the only thing that changes is the form in which your products are in. The reactants will still have the same amount of mass from the products as no products were removed or added, the structure changed, the mass did not.
