Is Iodine Found in Protein

These hormones have an important influence on a wide of biochemical reactions. Besides T3 and T4, iodine also exists as MIT, DIT, T3 and rT3, which are mainly bound with proteins in thyroid, but also function as free T3 and T4. Figure 15.6 shows the structure of iodinated hormones and their metabolism.

What is iodine considered?

Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements. The other halogens include fluorine (F), chlorine (Cl), bromine (Br) and astatine (At).

Is iodine a carbohydrate?

Even though they are both carbohydrates, iodine will not change colors when it gets exposed to sugar. This is because starch is made up of many, many sugar molecules chained together. Only the long chains found in starch are able to interact with the iodine.
