Potassium iodide (KI) and potassium iodate ... If a person consumes a dose of one of these chemical compounds, his or her thyroid may saturate with stable iodine, ...
Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Potassium iodide finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines. Aryl iodides are in turn used to attach aryl groups to other ...
Other sources state that pure potassium iodide solution in water was eventually used for most of the thyroid protection after this accident. [26] There is "strong scientific evidence" for potassium iodide thyroid protection to help prevent thyroid cancer. Potassium iodide does not provide immediate protection but can be a component of a general ...
[14] [15] Potassium iodide (KI) is typically used for this purpose. [16] However, unjustified self-medicated preventive administration of stable KI is not recommended in order to avoid disturbing the normal thyroid function. Such a treatment must be carefully dosed and requires an appropriate KI amount prescribed by a specialised physician.
Ingestion of this large dose of non-radioactive iodine minimises the uptake of radioactive iodine by the thyroid gland. [19] Before the advent of organic chelating agents, salts of iodide were given orally in the treatment of lead or mercury poisoning, such as heavily popularized by Louis Melsens and many nineteenth and early twentieth century ...
Four inorganic compounds are used as iodide sources, depending on the producer: potassium iodate, potassium iodide, sodium iodate, and sodium iodide. Any of these compounds supplies the body with the iodine required for the biosynthesis of thyroxine (T 4) and triiodothyronine (T 3) hormones by the thyroid gland.
The Wolff–Chaikoff effect is an effective means of rejecting a large quantity of imbibed iodide, and therefore preventing the thyroid from synthesizing large quantities of thyroid hormone. [7] Excess iodide transiently inhibits thyroid iodide organification. In individuals with a normal thyroid, the gland eventually escapes from this ...
Iodide transport is a key step in the biosynthesis of the thyroid hormones T4 and T3. [5] [6] For example, potassium perchlorate competitively inhibits the active iodide transport mechanism in the thyroid gland, which has the capacity to selectively concentrate iodide against a large concentration gradient.
