Question

Thyroxine (C₁₅H₁₁I₄NO₄) is a hormone synthesized by the thyroid gland and used to control many metabolic functions in the body. A physiologist determines the mass percent of thyroxine in a thyroid extract by igniting 0.4332 g of extract with sodium carbonate, which converts the iodine to iodide. The iodide is dissolved in water, and bromine and hydrochloric acid are added, which convert the iodide to iodate.
(a) How many moles of iodate form per mole of thyroxine?

Answer 1

We can infer that 4 moles of iodate are produced from 1 mol of thyroxine since all of the iodide is transformed to iodate.

Describe thyroxine.

The primary hormone that the thyroid gland releases into the bloodstream is thyroxine. It is the inactive form, and organs like the liver and kidneys convert the majority of it into the active form triiodothyronine.

What occurs if thyroxine levels are too high?

When your thyroid gland generates too much of the hormone thyroxine, you get hyperthyroidism (overactive thyroid). Your body's metabolism may speed up as a result of hyperthyroidism, resulting in unexpected weight loss and a swift or erratic heartbeat.

What distinguishes thyroxine and TSH from one another?

Your thyroid gland then releases T4 and T3 with the aid of the TSH. TSH is essential to the system's operation. Your metabolism, emotions, and body temperature are all influenced by thyroxine (T4), among other things.
