Monosaccharide Lab Report

Good Essays
A monosaccharide is a one-ringed sugar (part of the carbohydrate category) that is not bonded to any other molecules. A monosaccharide is a monomer of a disaccharide. A disaccharide is two monosaccharides bonded together. The prefixes “mono-“ and “di-“ indicate the amount of rings in the sugar. In this experiment, disaccharides were tested using an enzyme as part of a chemical reaction. A chemical reaction changes substances into different substances by breaking and forming chemical bonds. In a chemical reaction, there are two main parts: the reactants and the products. The reactants are the substances changed in a chemical reaction. The products are the substances created by the chemical reaction. In many cases of chemical reactions, substances called catalysts are utilized. Catalysts are substances that decrease the activation energy needed to start a …show more content…
In this case, we added the lactase solution (independent variable) to milk. The dependent variable of this experiment was milk. In this case, the amount of glucose produced in the milk (dependent variable) was measured. The constants of this experiment were the amounts of liquids (10 mL of milk and 1 mL of lactase), time to break down before testing (6 minutes), temperature, and type of container (test tube). The purpose of the experiment was to test the effect of the enzyme lactase on the milk solution. Because milk contains lactose (broken down by lactase to produce glucose and galactose), the purpose of this experiment was to test if milk contained glucose with the enzyme lactase. The milk was also tested by itself to see if glucose was present without lactase. If the lactase (independent variable) is added to the milk, then glucose will be present in the milk because the substrate (lactose in milk) matches the active site of the enzyme lactase and can therefore be broken down into glucose and

    Determination of fat in milk AIM: - To determine the fat content by using gerber method. Principle: - The milk is mixed with sulphuric acid and iso-amyl alcohol in a special Gerber tube, permitting dissolution of the protein and release of fat. The tubes are centrifuged and the fat rising into the calibrated part of the tube is measured as a percentage of the fat content of the milk sample. Apparatus: - Butyro meter, 10.75ml pipette,amyl alcohol, stoppers, gerber centrifuge, water bath. Reagents:-Sulphuric acid, amyl alcohol.…

    Gold electrodes were prepared after cleaning with H2SO4 and H2O2. Glucose oxidase and laccase were immobilized on the GO/Co/chitosan modified electrodes in a sodium phosphate buffer solution (0.1 M, Ph 7) for 8 h [12]. The electrochemical activities of enzymatic electrodes were measured using VersaSTAT3 (AMETEK, Princeton Applied Research, USA). Electrochemical measurements such as CV and EIS were carried out using an Au electrode with the assembled glucose oxidase, Ag/AgCl, and a Pt wire as the working electrode, reference electrode, and the counter electrodes, respectively [13]. The following parameters were used to measure EIS using a Nyquist plot: start frequency, 20 Hz; end frequency, was 0.01 Hz; and amplitude voltage, 10 mV.…

    The separatory funnel was used to separate glucose, ethyl cinnamate, and cinnamic acid. The purity of ethyl cinnamate and glucose were tested through IR spectroscopy, and the purity of cinnamic acid was tested by finding the melting point. Experimental Methods 0.604 grams the starting mixture of cinnamic acid, ethyl cinnamate, and glucose was weighed out then was placed into a separatory funnel. Diethyl ether (10 mL, 0.134916 mol) was then swirled into the mixture. Then DI water (10 mL) was added to form the aqueous layer.…

    • Sucrose can be broken down into glucose and fructose to produce energy. • Glucose is broken down into a pathway called “glycolysis” which produces pyruvate. Pyruvate then goes into the Citric Acid Cycle and produces ATP which is the energy needed in our bodies. • The first 2 steps of fructose breakdown is unique to fructose. • When Fructose is broken down, the enzyme fructokinase converts fructose to fructose-1-phosphate.…

    This is why the water molecules in Cell B had mostly moved out of the dialysis tubing to keep the concentration of water equal both outside and inside the cell. We also conducted the Benedict test for Cell A and Cell B. We saw that Cell A had no glucose, but Cell B had glucose. From this, we could see that both water and glucose moved through the selectively permeable membrane of the dialysis Cell B. The glucose moved inside the cell so that it could also balance out the concentration of water outside and inside the cell.…

    These materials were Whole milk, 10% acetic acid, coffee filters, ethyl acteate, 1% glucose solution, Fehling’s solution, Biuret’s test solution (.5% CuSO4), 10% NaOH, lactose, lactase, glucose test solution, ammonium molybdate solution, funnels, .1% ammonium oxalate solution, beakers (different sizes) , flasks(Erlenmeyer flasks) , test tubes, thermometer, hot plate, watch glass, Pasture pipettes, rubber policeman, boiling chips, labeling tube, small mortar and pestle and 4 glucose urinalysis test strips. This experiment was separated into three different separations. During the first separation the lab groups were to obtain 100 mL of whole milk into a 250 mL Erlenmeyer side arm flask. Then, heat the flask to precisely 40°C and make sure not exceed 40°C because anything over 40°C would start to denature the proteins of the milk. Once the milk is at 40°C the labs groups were to add 11.0 mL of the 10% acetic acid and stir continuously for approximately one minute.…

    During a reaction the bonds in the substrate are distorted and product(s) are released. A further example of globular proteins are coenzymes, small organic molecules, which collaborate with enzymes. Coenzymes are used during a process called dehydrogenation where (usually two) hydrogen atoms are removed from the substrate. The process starts when coenzyme (e.g. NAD) binds to the enzyme to another binding side beside the active side for the substrate.…
