Iodine is known to be crucial for life in many unicellular organisms [23] Phosphorylated tyrosines created with tyrosine kinases are fundamental signalling molecules in all animals and in Choanoflagellates [21] [22] and may be linked to the usage of tyrosine iodine compounds for similar roles. [23]
An iodide ion is I −. [2] Compounds with iodine in formal oxidation state −1 are called iodides. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate. Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability. [3]
Natural food sources of iodine include seafood which contains fish, seaweeds, kelp, shellfish and other foods which contain dairy products, eggs, meats, vegetables, so long as the animals ate iodine richly, and the plants are grown on iodine-rich soil. [114] [115] Iodised salt is fortified with potassium iodate, a salt of iodine, potassium, oxygen.
Plants uptake iodine from the soil through their roots and return the iodine when they decompose. [2] Fauna that consume plants may uptake this iodine but similarly return it to soils upon decomposition. [2] Some iodine may also be cycled into the freshwater hydrosphere through leaching and runoff, where it may return to the oceans. [1]
Of the halides, iodide usually is the best leaving group. Because of the weakness of the C–I bond, samples of organoiodine compounds are often yellow due to an impurity of I 2. A noteworthy aspect of organoiodine compounds is their high density, which arises from the high atomic weight of iodine.
Animals also benefit from iodine supplements, and the hydrogen iodide derivative of ethylenediamine is the main supplement to livestock feed. [5] Salt is an effective vehicle for distributing iodine to the public because it does not spoil and is consumed in more predictable amounts than most other commodities.
Thyroid peroxidase, also called thyroperoxidase (TPO), thyroid specific peroxidase or iodide peroxidase, is an enzyme expressed mainly in the thyroid where it is secreted into colloid. Thyroid peroxidase oxidizes iodide ions to form iodine atoms for addition onto tyrosine residues on thyroglobulin for the production of thyroxine (T 4 ) or ...
Mutations in the gene encoding iodotyrosine deiodinase can affect enzyme function and be detrimental to human health. Iodide is an essential micronutrient for health in mammals. [24] Low levels of iodide either through the diet or through iodide metabolism are associated with hypothyroidism, mental retardation, goiter, and developmental defects.
