Iodine is necessary for the synthesis of Thyroxine hormone.

Thyroxine Hormone:
Thyroxine hormone is produced by the thyroid gland, which is present in the neck region. This hormone is responsible for regulating the metabolic rate of the body. It helps in the growth and development of the body, and also affects the heart rate, body temperature, and energy levels.

Iodine and Thyroxine hormone:
Iodine is an essential component in the synthesis of Thyroxine hormone. The thyroid gland takes up iodine from the bloodstream and combines it with an amino acid called tyrosine to produce Thyroxine hormone. Without iodine, the thyroid gland cannot produce enough Thyroxine hormone, which can lead to various health problems.

Iodine deficiency:
Iodine deficiency is a common problem in many parts of the world, especially in developing countries. It can lead to several health problems, including goiter (enlarged thyroid gland), mental retardation, and developmental delays in children. To prevent iodine deficiency, it is essential to consume iodized salt or foods that are rich in iodine, such as seafood, dairy products, and eggs.

Conclusion:
In conclusion, iodine is necessary for the synthesis of Thyroxine hormone, which plays a crucial role in regulating the metabolic rate of the body. Iodine deficiency can lead to various health problems, and hence it is essential to consume iodized salt or iodine-rich foods to maintain good health.

Iodine is necessary to thyroxine for the metabolism of fat, carbohydrates and proteins
