Iodine And Your Health
Iodine chemical reacts least of the electropositive halogen rather than the chemical
astatine. The existence of iodine is not free in state in the environment. Compared to the other halogen members of
Group VII as per the Periodic Table, when iodine is released from the composite, the chemical iodine figures forms
diatomic molecules (I2).
Iodine and its elements are largely used in the production of medicines, photography and dyes. The existence of
iodine is unusual in the solar system and Earth. These elements are easily soluble in water and highly concentrated
in seawater. The mechanism of iodine helps to determine the required levels of iodine in the animals and plants and
considered as the essential element in all living organisms.
Iodine is considered essential in the use of pharmaceuticals, medicine, antiseptics, food supplements, dyes,
halogen lights, catalysts, water purifying and starch detection. The medicine tincture has the presence of 10%
iodine in the ethanol base and it is considered as an essential component in healing of infections and purifying
the surface of the drinking water. Lugol’s iodine free of alcohol and iodophor antiseptics also helps in serving as
an effective medicine for the above purpose.
Iodine elements form an essential role in the field of organic chemistry. The essential element iodine plays the
role of constituents for thyroid hormones called thryroxine (T4) and triiodothyronine (T3) in the biological
studies. The constituents are made from condensation products of the amino acid tyrosine and are kept in the
iodine, containing molecule called thymoglobulin. The constituents T4 and T3 consist of four and three atoms of
iodine per molecule. The thyroid gland absorbs the iodide from the blood and exhausts these hormones into the blood
for performing a regulated action by the second hormone called the TSH from the pituitary.
The thyroid hormones play an important role in the biological studies. These hormones react upon the gene
transcription for regulation of the basal metabolic rate. The complete deficiency of the thyroid hormones can lead
to the reduction in the basal metabolic rate up to an extent of 50% and in the excessive production of the thyroid
hormones the basal metabolic rate can be increased up to the extent of 100%. The hormone T4 acts mainly upon the T3
hormone and it is called the biologically active hormone.
Men and women should consume 150 micrograms of iodine per day as prescribed by the United States Food and Drug
Administration. This consumption forms an essential part in the production of thyroid hormone. Some of the natural
sources of iodine are sea foods like kelp, plants grown on iodine rich soil. Iodized salt derived from iodine
provides salt for human consumption.
The areas like typical inland areas, semi-arid equatorial climates where the existence of marine foods is
unavailable are prone to iodine deficiency and this leads to hypothyroidism, fatigue, mental slowing, goiter,
depression, weight gain and low body temperatures. The deficiency in iodine also leads to mental retardation, birth
of babies and small children with hypothyroid. The inclusion of iodized salt in the food has certainly reduced the
problems arising from iodine in the wealthier nations. Scientific results have proved that during the year March
2006, the problem of iodine deficiency has remained as a serious threat in the developing world.
