The role of iodine in mammary tissue is related to fetal and neonatal development, but its role in the other tissues is not well known. [8] It has been shown to act as an antioxidant [8] and antiproliferant [9] in various tissues that can uptake iodine. Molecular iodine (I 2) has been shown to have a suppressive effect on benign and cancerous ...
Ripening can be induced by abscisic acid, specifically the process of sucrose accumulation as well as color acquisition and firmness. [19] While ethylene plays a major role in the ripening of climacteric plants, it still has effects in non-climacteric species as well. In strawberries, it was shown to stimulate color and softening processes.
Iodine rarely occurs naturally in mineral form, so it comprises a very small portion of rocks by mass. [2] Sedimentary rocks have higher concentrations of iodine compared to metamorphic and igneous rocks. [4] Due to the low concentration of iodine in rocks, weathering is a minor flux of iodine to soils and the freshwater hydrosphere. [1]
iodine: 53: 5ac: Iodine has a role in biochemical pathways of organisms from all biological kingdoms, indicating it is uniformly essential to life [48] Widely used in medicine, mainly for treatment of goitre and for its antibacterial properties. [11] Highly toxic to humans in its elemental form. [11] iridium: 77: 1a
Inorganic iodine enters the body primarily as iodide, I −. After entering the thyroid follicle (or thyroid follicular cell) via a Na + /I − symporter (NIS) on the basolateral side, iodide is shuttled across the apical membrane into the colloid via pendrin after which thyroid peroxidase oxidizes iodide to atomic iodine (I) or iodinium (I ...
These iodine compounds are hypervalent because the iodine atom formally contains in its valence shell more than the 8 electrons required for the octet rule. Hypervalent iodine oxyanions are known for oxidation states +1, +3, +5, and +7; organic analogues of these moieties are known for each oxidation state except +7.

For example, Iodotyrosine deiodinase is a mammalian enzyme with the unusual function of aerobic reductive dehalogenation of iodine- or bromine-substituted organic substrates. [6] Bromoxynil and ioxynil herbicides have been shown to undergo a variety of environmental transformations, including reductive dehalogenation by anaerobic bacteria.
