Iodide

Description

Iodide, also known as iodide ion or iodide salt, belongs to the class of inorganic compounds known as homogeneous halogens. These are inorganic non-metallic compounds in which the largest atom is a nobel gas. In fact, iodides are greatly present and available in the sea, where algal phytoplankton, the basis of marine food-chain, acts as a biological accumulator of iodides, selenium, (and n-3 fatty acids) :; Antioxidant biochemical mechanism of iodides, probably one of the most ancient mechanisms of defense from poisonous reactive oxygen species:; An Iodide is an iodine atom with a -1 charge. The chemical test for an iodide compound is to acidify the aqueous compound by adding some drops of acid, to dispel any carbonate ions present, then adding lead(II) nitrate, yielding a bright yellow precipitate of lead iodide. Iodide can function as an antioxidant as it is a reducing species that can detoxify reactive oxygen species such as hydrogen peroxide. Iodide is an extremely strong acidic compound (based on its pKa). Iodide exists in all living organisms, ranging from bacteria to humans. Algae that contain the highest amount of iodine (1-3 % of dry weight) and peroxidase enzymes, were the first living cells to produce poisonous oxygen in the atmosphere. Aqueous solutions of iodide dissolve iodine better than pure water due to the formation of complex ions:. iodide can be converted into iodide; which is catalyzed by the enzyme sodium/iodide cotransporter. In humans, iodide is involved in thyroid hormone synthesis. Outside of the human body, Iodide has been detected, but not quantified in, several different foods, such as lupines, strawberries, moth beans, asian pears, and swedes. This could make iodide a potential biomarker for the consumption of these foods. Compounds with iodine in formal oxidation state -1 are called iodides. Most ionic iodides are soluble, with the exception of yellow silver iodide and yellow lead iodide. Over three billion years ago, blue-green algae were the most primitive oxygenic photosynthetic organisms and are the ancestors of multicellular eukaryotic algae (1).
