BIOLOGICALLY IMPORTANT MOLECULES Abstract Compounds containing the element carbon‚ called organic compounds‚ are the most important substances that make up living organisms. There are thousands and thousands of different organic compounds. To identify the major types of organic compounds in living organisms ‚ several biochemical test were used . Introduction Organic molecules are those primarily made up of carbon‚ hydrogen and oxygen. The common organic compounds of living organisms are

infection. Causes of Hypothyroidism Radiation therapy can also cause hypothyroidism. When radiation damages the cells‚ the thyroid gland has to work harder. Radioactive iodine treatment can also destroy the thyroid gland. Surgery and medications can also cause an underactive thyroid. The human body does not produce iodine‚ and iodine deficiency can cause hypothyroidism.

determined by analyzing the amount of iodine (I2) formed. Two chemical reactions are useful to determining the amount of iodine is produced. 1) I2(aq) + 2S2O32-(aq) 2I-(aq)+S4O62-(aq) 2) I2(aq) + starch Reaction 2 is used only to determine when the production of iodine is occurring by turning a clear colorless solution to a blue color. Without this reaction it would be very difficult to determine how much iodine is being produced‚ due to how quickly thiosulfate and iodine react. However this reaction

protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine residues in thyroglobulin molecules‚ inside the follicle cell.
