    Iodine Isotopes are the atoms that have in their nucleus an atomic number corresponding to the chemical behavior of that element. Since isotopes have the same number of protons‚ they all have identical chemical behavior. But‚ however‚ since their neutron numbers are different the isotopes of the same element may have different radioactivity. An isotope that is radioactive is called a radioisotope like iodine‚ which is important in our health. In radioactivity‚ the nucleus of an unstable isotope

    INTRODUCTION Iodine deficiency disorders are still very much prevalent in the world today. Two billion people‚ estimated by the WHO‚ still lack a sufficient level of iodine in their diets which leads to a range of disorders known as iodine deficiency disorders (IDD). So what is iodine? Iodine is an essential micronutrient in the diet which is used by the thyroid gland (located in the throat) to produce thyroid hormones which help control the body’s metabolism. The two most important thyroid

    Iodine deficiency is a major threat to the health and development of the world‚ predominantly among toddlers and pregnant women in low-income countries. It is a significant public health problem in 130 countries and affects 740 million people. An estimated one-third of the world’s population is currently susceptible to the risk of iodine deficiency. Iodine is a vital nutrient for the proper functioning of the thyroid gland‚ which regulates growth and metabolism. Iodine deficiency is the primary cause

    Iodine Test for Starch Introduction and Hypothesis: In this experiment‚ we used iodine to test for starch in certain solutions. Iodine separates starch from polysaccharides‚ monosaccharides‚ and disaccharides. Starch is a curled polymer of glucose and iodine interacts with molecules‚ which changes the color of the molecules to a kind of black color. Iodine does not respond with carbohydrates that are not curled or coiled‚ thus the color stays yellowish brown. A black color result means that starch

    • 2 Pages

    Iodine is an element that is critical for normal function of the thyroid gland‚ which is a key regulator of the body’s basic metabolic rate. Iodine is a micronutrient‚ meaning we require only small amounts of it. For example‚ adults need about 150 micrograms of iodine in the form of iodide ion per day. However‚ an insufficient supply of iodide via diet and drinking water causes the non-cancerous enlargement of the thyroid gland known as goiter. Prolonged lack of iodide can lead to loss of thyroid

    JULIA SELORMEY BIO 111 Iodine Description: Is a trace mineral that your body uses in small amounts to synthesize thyroid hormones that are necessary for regulating the body growth‚ development‚ metabolism and body temperature. Most of the iodine in the body is found in the thyroid gland‚ but is found also in the blood and muscles. The body contains approximately 20 to 30 mg of iodine which is mostly stored in the thyroid gland located in front of the neck. Food sources: Milk is the major

    is most effective‚ this aim will be carried out as an iodine clock reaction. The goal of this aim is to find out what catalyst is best to make this reaction occur at the fastest rate. 3. Determine the effects of the presence of ethanol on the rate equation. It is known that ethanol effects hydrogen peroxide and therefore it has an effect on the rate equation. This aim will find out the effect of ethanol by carrying out the iodine clock reaction with and without ethanol present and the
