Date of Experiment: September 10th‚ 2013 Organic Chemistry II – CHLB330 Name: Symone E. MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

“Studies by Mayo Clinic revealed that to decelerate the digestion of carbohydrate‚ you need between 4‚000 to 6‚000 mg of bean extract or phaseolamin. Unfortunately‚ many carb blockers in the market have lower than 4‚000 mg of phaseolamin. In reality‚ a majority contain well below the recommended dosage which is a measly 500mg of white kidney bean extract. They also found that there is no sign of weight loss during the slowing down of the digestion of carbs” (Milone 2008). Students from the Biology department

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down

Introduction The Digestive system breaks down the ingested food into absorbable forms of nutrients and absorbs nutrients‚ ions and water from the external environment of the body. It is designed to maximize digestion and absorption. The functional structures of the digestive system are the passage‚ the glands like salivary glands‚ gastric glands‚ pancreatic‚ intestinal glands and liver. Also‚ the four layers of the digestive system are mucosa‚ submucosa‚ muscularis and serosa. The digestive system

making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose‚Lactose‚Sucrose‚and Starch.The main thing that make some of these carbohydrates different from each other is if it’s a Monosaccharide‚ Disaccharide‚or Polysaccharide. Monosaccharide are basic sugars

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

Who Took Jerell’s iPod? Lab Purpose: Standardized Tests The purpose of testing the organic nutrients (vegetable oil‚ glucose‚ starch‚ powdered egg white) with each of the different indicators (brown paper towel‚ benedicts‚ iodine‚ biurets) was to determine the color it would turn with positive traces of the nutrient. The purpose of testing just the Distilled H2O was to determine the color it would turn with negative traces. Nutrient in the Different Foods The purpose of testing each of the
