Structures of the complexes formed in aqueous solutions between zinc(II) and iodide ions have been determined from large-angle X-ray scattering, Raman and far-IR measurements. Intraluminal zinc is present in several different forms after a meal as a result of digestive processes that release zinc from food components and endogenously secreted zinc. Zinc mineral has been known as a supplement for diabetics due to its deficiency in diabetics. Yuji Mikata, Shoko Fujii, Masami Naemura, Kyoko Takahashi, Yuka Noguchi.
