Iodine

Week 3 – LOM Assignment The thyroid is responsible for taking iodine and converting it into thyroid hormones which are released into the blood stream and transported throughout the body where they control metabolism.1 The thyroid is a vital part of the human body as every cell in the body depends on it for metabolic regulation. Too much or too little thyroid hormone secretion can result in hyperthyroidism or hypothyroidism. Hyperthyroidism is caused when the thyroid secretes too many thyroid hormones

noting the time taken for the starch substrate to be broken down, that is, when it is no longer gives a blue-black colour when tested with iodine solution. This time is referred to as the achromatic point. Equipment: v Amylase solution 0.1% v Starch Solution 1.0% v Distilled water v Iodine in potassium iodine solution v White tile and polythene pipette v Graduate pipettes or syringes v Test tubes in rack v Beaker (used as water bath)

as ‘butterfly-shaped’ as it is composed of two connected lobes. See image: The two main hormones secreted by the thyroid gland are tetraiodothyronine (thyroxine or T4) and triiodothyronine (T3). Both hormones have a peptide structure containing iodine (three atoms in T3 and four in T4).These two hormones regulate growth and development as well as metabolism. They both speed up the rate of the body’s metabolic reactions, which in turn regulates body temperature (when energy is used in metabolic

to boron on semen quality was conducted on boars. Supplemental dietary boron enhanced sperm velocity characteristics and possibly normal morphology without influencing other measures of sperm production and semen quality (Korkmaz et al., 2011). The boron group’s abstinence time was found to be longer than that of the control group (Naghii and Saman, 1997a). Korkmaz et al., (2011) diagnosed oligozoospermia for one of the first two semen samples while the other had a diagnosis of asthenozoospermia;

with a good prognosis (outlook for survival). Follicular carcinoma is the second most common type of thyroid cancer, and accounts for approximately one out of 10 cases. It is found more frequently in countries with an inadequate dietary intake of iodine. Follicular carcinoma is also a differentiated form of thyroid cancer. In most cases, it is associated with a good prognosis, although it is somewhat more aggressive than papillary cancer. Follicular carcinomas do not usually spread to nearby lymph

depends on iodine to make the hormones that regulate energy and metabolism. But compounds called goitrogens in cruciferous veggies (such as broccoli, cabbage, cauliflower, and kale) can block the body's absorption of iodine. The solution: Enjoy these veggies steamed since heat deactivates goitrogens. To further safeguard iodine levels, season one dish per day with powdered kelp. This salty sprinkle delivers 485 mcg of organic iodine. which is better utilized by the thyroid than the iodine in table

Arlet Morera Castillo Paper 1 Title: BIOLOGICALLY IMPORTANT MOLECULES, Carbohydrates, Proteins, Lipids, and Nucleic Acids. This paper will describe the importance of various organic molecules when we follow perquisite steps to unveil them in a few conducted tests. List of Authors: Arlet Morera Castillo Introduction: It is beneficial for us humans to start an early knowledge of the molecules that compose the things surrounding us and even ourselves. Scientifically that eagerness to comprehend

solution was added to one of the test tubes and sodium iodine to the other. After the two test tubes containing the solutions were thoroughly mixed, bromine water was added drop by drop, checking for any change during the addition of each drop of bromine water. Any changes in color or texture were recorded. The next two trials were conducted in the same manner, but with the following exceptions. The sodium halide salts used for trial two were sodium iodine and sodium bromine, and the water used was chlorine

Chemistry is the study of matter and energy and the interaction between them. Chemistry sometimes referred to as the central science because it connects other sciences to each other, such as biology, astronomy, medicine, physics, geology and environmental science. Chemistry is everywhere in the world around us; It 's in the food we eat, water we drink, medicine we take, clothes we wear, air, even the body is made of chemicals. Chemical reactions occur when we breathe, eat, run, or lay down. We are

starch. The disappearance of the yellow color of the triiodide could be used as an endpoint. However, the change is subtle and difficult to detect precisely since S4O6-2 and other ions present are also clear, For this reason, we make use of the iodide/iodine already present in the solution as an indicator. The addition of starch to a solution that contains triiodide or iodide creates a reversible blue complex that is
