Characteristic deficiency disease results when compound is lacking in diet or poorly absorbed/utilized. 1 out of 3 ppl in developing countries are affected by vitamin and mineral deficiencies who. Type (cid:883) receptors (cid:523)cytosolic(cid:524) respond to steroid hormones like . Micronutrients 1: control type ii steroid hormone receptors and have global health implications. Intracellular proteins (cytosolic or nuclear) that bind to hormones and become tf (for gene expression) Like thyroid hormones, retinoic acid, and calcitriol (1,25-duhydroxy vitamin d) Type ii receptors (nuclear) were found to have similar structure, but bind to steroid and non-steroid ligands. Iodine content of most foods is low (sea salt has no iodine) In gut, iodine (mineral form) iodide (circulating form)
