Iodine in biology
Iodine in biology refers to the essential role that the chemical element iodine plays in various biological processes. Iodine is a trace element that is vital for the normal growth and development of most life forms, especially mammals.
Role in biology[edit]
Iodine is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), which regulate various physiological processes in the body. These hormones are produced by the thyroid gland and are crucial for normal growth and development, as well as for the regulation of metabolism.
Iodine is also involved in the function of the immune system, where it acts as an antioxidant and a regulator of cell growth and differentiation. It is also essential for the normal development of the central nervous system in fetuses and young children.
Dietary sources[edit]
The primary dietary sources of iodine include seafood, iodized salt, and certain types of seaweed. Dairy products and grains can also be good sources of iodine, depending on the iodine content of the soil where the animals are raised or the crops are grown.
Iodine deficiency[edit]
Iodine deficiency is a serious health problem that can lead to goiter (an enlarged thyroid gland), hypothyroidism (reduced function of the thyroid gland), and cretinism (severe physical and mental retardation in infants and children). It is the most common cause of preventable mental retardation worldwide.
