Of Seliwanoff's Test To Distinguish Between Ketoses And Aldoses
Seliwanoff’s test is used to distinguish between aldoses and ketoses. This test uses 3N hydrochloric acid as the dehydrating agent as resorcinol as the condensation reagent. When mixed with Seliwanoff’s reagent, ketopentoses react within two minutes to form a cherry red condensation product. Aldopentoses react after two minutes to form a blue-green condensation product, which may further change to a peach product.

    Summary Of Casein Unknown # 7

    Glucose exposure resulted in a yellow color change proving that Unknown #7 fermented glucose and produced an acid but when exposed to Sucrose Unknown #7 produced a red color change indicating that it was a non-fermented of sucrose which was reflected with an alkaline bi-product. The Enterotubes showed that Unknown #7 was an "enteric" bacterium with a score of "46141" Lysine, Adonitol, Lactose, Dulcitol/Phenylalanine, and Harnstoff/Uree were all negative, while Ornithine, Arabinose, and Sorbitol were proven to be positive. The IMViC test identifies members of Enterobacteriaceae and included Indole that tested negative, Methyl Red which produced a red color change showing that Unknown #7 could ferment glucose to acidic ends, Vogves Proskaer which tested negative because Unknown #7 failed to convert those acidic bi-products back to neutral ends, and Citrate which tested positive with a blue color change and growth on the medium because Unknown #7 was able utilize citrate. The Nitrate Reduction test displayed Incomplete Reduction with a red color change when Solution A and B were added meaning that it could only reduce NO3- to NO2-…

    Erlenmeyer Synthesis

    The Fehling’s test was done to show the presence of carbohydrates. Two small test tubes were used and 5 mL of Fehling’s reagent was added to it. Five drops of 1% glucose was added to one test tube, the control. This tube was then boiled and if a brown-red precipitate was formed, it would indicate that there was a carbohydrate present. The other tube had 5 mL of the Fehling’s reagent put in it and five drops of the filtrate after the ethyl acetate was gone and the filtrate had been cooled. If this created a brown-red precipitate, it would indicate that there was a carbohydrate…

    The amount of glucose and glycerol were determined from the homogenate sample as well. Samples A(+) and B(-) were used to determine glucose. Sample A had 8mg/ml amylogloucosidase in .2M citrate buffer, pH 5.0 and was incubated at 37° Celsius for two hours to allow for the enzyme to digest the glycogen. Sample B was the control, where only .2M citrate buffer, pH 5.0 was added which was used to measure the amount of free glucose. While incubating, glycerol was determined by using 3 ml triglyceride reagent incubated at 37°celsius for 5 minutes. After warmed, 30 microliters of homogenate was added to…

    Spit Lab

    The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also, to test the chewed cracker, the one that didn’t have a reducing sugar, for the presence or absence of a reducing sugar with the saliva in it. Adding on, another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab, the objectives were to test for the presence or absence of carbohydrates, lipids and proteins in several test samples. In the starch test, the objective was to find the substances that contain starch. In the starch test, iodine was used. In the reducing sugar test, the objective was to find the test materials that have a reducing sugar. In the reducing sugar test benedicts was used. In the grease spot test, the objective was to find all the samples that had a lipid. Another one of the lipid tests were the dye test which was a more specific test to find the substances that all contained a fat by using a solution of Sudan 4 and water. The protein test’s purpose was to determine all the test materials that contained a protein by using biuret solution. The procedure for the Spit lab was to perform the starch test and reducing sugar test on both crackers. Then chew up the cracker that doesn’t have reducing sugars. Next, test the sample for a reducing sugar. The results of the Chemical Aspects lab were that starch, potato juice, cracker solution, and cereal contain starch. In the reducing sugar test glucose, fructose, lactose, and milk contain a reducing sugar. In the grease spot test, salad oil, milk, and chips are lipids. In the dye test, salad oil and chips are fats. Egg albumin, cereal, and cracker mixture show that they are proteins. In the Spit lab the saliva and cracker test showed up positive. The starch test for saltine was positive. The reducing sugar test for saltine was…

    Enzyme

    For Activity A, we first tested enzyme activity. First, we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then, we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that, we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that, we placed the test tube filled with catalase in a boiling water bath for five minutes. While we were waiting, we rinsed the unlabeled cup we used earlier when we tested enzyme activity. Then we used a H2O2 syringe to transfer 10 mL of H2O2 into the rinsed unlabeled cup. After five minutes, we transferred 1 mL of the boiling catalase into the unlabeled cup with H2O2 in it with an unused transfer pipet and observed the results. After testing the effect of boiling on enzyme activity, we tested for catalase in living tissue. First, we rinsed the unlabeled 60 mL cup we used earlier. Then, we used a scalpel to cut a small piece of liver. After that, we macerated the piece of liver with a glass rod. When the liver was macerated enough, we put it in a cup with 10 mL of H2O2, which was transferred into the cup with a H2O2 syringe. Lastly, we observed the cup.…

    Macromoleules of Life

    In my first experiment to test for proteins the egg white with the Bluret reagent should come out positive for being a protein. The pepsin in the Bluret reagent should be positive and should be a protein. The test for sugar in the Bluret reagent should be negative and I don't think it is a protein. The test with the distilled water with the Bluret reagent should be negative and is not a protein. In the second experiment to test for glucose with the Benedict reagent sugar should be positive for glucose. Starch mixed with the Benedict reagent is probably positive for glucose because it is a polysaccharide. Onion juice mixed with Benedict reagent is probably positive for glucose because it is a fructose. Distilled water with Benedict reagent should be negative for glucose. The third experiment to test for starch using with and without the IKI reagent by looking under a microscope a slice of potato cells should have several shapes to it and with the IKI reagent should look have more of a stronger shapes and color to it. The onion cells should have a more stringy look to it and with the IKI more color. The fourth experiment is testing for lipids using the Sudan III on a potato, onion, oil and dH2O. I believe the oil will determine it is a lipid. The fifth experiment the chemical bonding of mixing an egg yolk, vegetable oil and vinegar should make mayonnaise as long as you continually mix a good amount of vegetable oil…

    Effect of Heat on Vitamin C

    Method to test hypothesis: The hypothesis can be tested by first determining the amount of ascorbic acid needed to decolourize 3mL of DCPIP solution, and calculating the concentration of Vitamin C in the ascorbic acid. Next, determine the amount of fruit juice needed to decolourize 3mL of DCPIP solution, and calculating the concentration of Vitamin C in the fruit juice initially. Then, heat a few test tubes of fruit juice in a boiling water bath for different periods of time- 3min, 7min, 11min, and 15 min. The test tubes should hold amounts of fruit juice that are more than the amount of fruit juice needed to decolourize 3mL of DCPIP initially. Take out the test tubes at the designated times and calculate their concentrations. Finally, the concentrations can be compared and the trend can be shown.…
