Introduction : The gall bladder is an organ in the body that retains bile produced in the liver and supplies it to the small intestine for digestion. The gall bladder is also a source of cholesterol, and when the concentration of cholesterol gets too high it will come out of solution and accumulate to form gallstones. 3 These gallstones will collect and irritate the lining of the gall bladder, which can cause sever pain, nausea, vomiting, and can block the bile duct. 3 Today gallstones are removed by disintegrating them in the gall bladder and the whole organ is removed through a small incision. 3 The average human has about 200 g of cholesterol primarily in the spinal cord, brain, and nervous tissue. 3 Because cholesterol is insoluble in water; it is transported through the bloodstream bound to lipoproteins, high-density (HDL) and low-density lipoproteins (LDL). HDL cholesterol is beneficial, where as LDL cholesterol leads to gallstones and is deposited on the walls of arteries. 3 By isolating cholesterol it allows this compound to be more easily studied. Because of the health risks related to LDL levels, studying cholesterol is beneficial to the overall health of humans. For this experiment cholesterol is isolated from human gallstones. An IR analysis will be conducted and the melting point will be taken to confirm the identity of the product and the percent recovery will be calculated. The structure of cholesterol is shown below.
