MAIN USES - Iodide ● Because of its excellent function to absorb X-ray, iodine is used as a substituent when various contrast-media for diagnostic purposes are produced. ● Some of the pharmaceuticals and crop protecting agents have iodine as the substituent ● Iodine, being the simple substance and having an anti-biotic function by nature, is used as a raw material for the production of various bactericides or disinfectants .
MAIN USES – Iodide Cont’d ● Iodine compounds are added to table salt and feed to treat and prevent "iodine deficiency symptom". ● Iodine has a wide range of uses, for example, in photo- sensitizers, catalysts, stabilizers and polarizing films on the liquid crystal display. Also, iodine compounds are widely used as intermediates for various reactions because of their high reactivity.
Potassium Iodide (KI) ● KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. ● The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
Potassium Iodide (KI) Cont’d ● Potassium iodide is used to loosen and break up mucus in the airways. This helps you cough up the mucus so you can breathe more easily if you have long-term lung problems (e.g., asthma, chronic bronchitis, emphysema). This medication is known as an expectorant ● The FDA has approved two different forms of KI (potassium iodide), tablets and liquid, that people can take by mouth after a radiation emergency involving radioactive iodine.
Health effects of iodine ● Many medicines and cleansers for skin wounds contain iodine. ● Iodine is a building material of thyroid hormones that are essential for growth, the nervous system and the metabolism. Humans that eat little to no bread can experience iodine shortages. This condition is rare now as table salt is dosed with a little iodide. Large quantities of iodine can be dangerous because the thyroid gland will labor too hastily. This affects the entire body; it causes disturbed heartbeats and loss of weight. ● Elemental iodine, I 2 , is toxic, and its vapor irritates the eyes and lungs. All iodides are toxic if taken in excess. ● Iodine 131 is one of the radionuclides involved in atmospheric testing of nuclear weapons, which began in 1945, with a US test, and ended in 1980 with a Chinese test. It is among the long-lived radionuclides that have produced and will continue to produce increased cancers risk for decades and centuries to come.
Iodine in the environment ● Iodine is added to nearly any kind of salt that is applied. It is an ingredient of bread, sea fish and oceanic plants. Iodine is naturally present in the ocean and some sea fish and water plants will store it in their tissues. ● Iodine can be found naturally in air, water and soil. The most important sources of natural iodine are the oceans. About 400.000 tons of iodine escape from the oceans every year as iodide in sea spray or as iodide, hydrochloric acid and methyl iodide, produced by marine organisms. Much of it is deposited on land where it may become part of the bio-cycle.
Ph Phas ase e Di Diag agram -Glyceride(Triglycerides) • a fatty acid ester of glycerol. • The triglycerides are esters of glycerol with long chain fatty acids. These three fatty acids in triglycerides may be same or different.
Phase Diagram (Cont) As shown over in the Phase diagram below i n the fatty acids of a glyceride, the lower is the melting point and the more likely the glyceride will exist as a liquid at room temperature(Black Line ).
Phase Diagram (Cont) . A triglyceride contains three fatty acids that are made up of hydrogen, carbon and oxygen. In a single free fatty acid if there is a hydrogen missing from the carbon chain creating a double bond then it is considered to be unsaturated. In comparison saturated fat contains no missing hydrogen’s. The molecular structure of Triglyceride can effects its physical state .
GLYCERIDE Janelle Anderson
What Is A Glyceride? Any of various esters formed when glycerol reacts with a fatty acid. The fatty acids can react with one, two, or all three of the hydroxyl groups of the glycerol, resulting in mono-, di-, and triglycerides, respectively. Triglycerides are the main components of plant and animal oils and fats. Esters: any of a class of A vegetable oil is a compounds produced by triglyceride extracted from reaction between acids and a plant .Vegetable oils are alcohols with the elimination composed of triglycerides, of water. as contrasted with waxes which lack glycerin in their structure.
Health Benefits of Glyceride Constipation: Glycerin suppositories are often prescribed for the short-term treatment of constipation. They work by lubricating and mildly irritating the lining of the intestines, causing the muscles to contract, while pulling water from the intestines into the stool to make it easier for the stools to pass. Triglycerides are necessary for good health in several very distinct ways. They provide stored energy to the body, and their levels can serve as a warning sign of potentially dangerous conditions and risk factors. High triglycerides can even trigger a person to make healthy lifestyle changes, and monitoring their levels can serve as a way to evaluate the success of those changes
Risks When Exposed To Glyceride While glycerin itself is not toxic, it can irritate the lower bowel as it pulls water from surrounding tissues. Dehydration of the tissues of the rectum and lowermost intestine can lead to cramping of the smooth muscle that lines the bowel. Side effects from this treatment can include nausea, vomiting, abdominal pain and etc.
What is a Triglyceride? Triglycerides are formed from a single ● molecule of glycerol combined with three fatty acids on each of the OH groups and make up most of the fats digested by humans. It is the main constituent of vegetable oil and animal fats ● Triglycerides comprise the largest proportion of fats (lipids) in the diet, in the adipose tissue, and in the blood. High levels of triglyceride are considered as a risk factor for ischemic heart disease. This is especially true because people with high triglycerides often have other conditions, such as diabetes and obesity, that increase the likelihood of developing cardiovascular disease.
Triglycerides store fat and are used by the body to create energy and serve as building blocks for cells.
Health Risks for Triglyceride Triglyceride levels can provide a warning of an underlying disease. The Mayo Clinic says that high triglyceride levels can signal the presence of hypothyroidism, kidney disease, liver disease or type 2 diabetes. They can even be a sign of a rare genetic condition in which the body cannot properly convert fat to energy. If you have a high triglyceride level, your doctor can screen you for other illnesses that might be related.
How Glyceride is Used In The Industry Soaps are formed from the reaction of glycerides with sodium hydroxide. The product of the reaction is glycerol and salts of fatty acids. Fatty acids in the soap emulsify the oils in dirt, enabling the removal of oily dirt with water.
How to Make Glycerin Soap Buy supplies. Craft stores sell glycerin, which is a soap base, in solid, meltable blocks. If you're feeling ambitious, you can make your own glycerin, but it's easier to buy blocks of clear glycerin, white glycerin, or a different color. Clear glycerin soap always looks a little transparent, no matter what color you choose. Supplies: Essential oils. Craft stores sell essential ● oils meant for use in glycerin soap. Rubbing alcohol. If you don't already ● have some in your medicine cabinet, pick up a bottle at the drugstore.
Step 2. Melt the glycerin in a double boiler. Cut off as much glycerin as you need to fill the soap molds you bought, then slice it into small pieces that will be easier to melt. Place the glycerin pieces in a double boiler, fill the boiler with water, and place it over medium heat. Continue heating the glycerin until it is completely melted. If you don't have a double boiler, you can make ● one. Find two pots, a large one and a smaller one that fits inside. Fill the larger pot with a few inches of water. Set the smaller pot inside the larger pot so that it floats on the water. Place the pots on a burner over medium heat. Put the glycerin chunks into the dry, smaller pot and allow them to melt. You can also melt the glycerin in the ● microwave.
