Abstract: Fermentation of sucrose with brewer yeast catalyst was successfully conducted to yield ethanol with 70.2 % conversion of sucrose. Based on the graph of Refractive Index vs % ethanol (v/v), 32.8% of ethanol was determined to be in the distillate solution with corresponding Refractive Index of 1.3555 Statement and purpose The purpose of this experiment was to determine the % of ethanol (v/v) in the resulting solution and the % conversion of sucrose Introduction The fermentation 17.1 g…

It is also called anabolism or biogenesis. It is a enzyme-catalyzed method in which substrates are transformed into complex products. In this process simple compounds change or convert into other compounds or they join together to form macromolecules. Example: In this process gluneogenesis is responsible for the production of glucose from non carbohydrate originator. Actually biosynthesis is an enzyme-catalyzed process in which substrates are converted into complex compounds. 1. Biosynthesis…

Recording initial rate Amount of enzyme Temperature Volume of hydrogen peroxide solution Size and type of test tubes Hydrogen peroxide Cap the test tube immediately with the gas pressure sensor once the hydrogen peroxide is poured inside to be able to record the most accurate data. Be very carful when adding drops of enzyme because even the slightest drop can affect it completely. To have the most accurate measurements use micropipette and use 10 micro-liters of enzyme. Be sure to…

which gave an IC50 value of 5.87, 4.19 and 3.83 µg/ml on each cell line respectively. Figure 3. Cytotoxic effect of pulchranin A (1) and doxorubicin (2) on HEPG2 (a), HCT (b) and MCF-7 (c) cell lines. The ability of pulchranin A to inhibit CDKs enzymes (Figure 4) was assessed on human breast cancer cell lines MCF-7 cells, as they were the most sensitive to our compound and showed the least cell…

Investigative Question Does sugar or salt effect the freezing point and period of time that water takes to freeze? Hypothesis If you add either sugar or salt to water it will affect the freezing point of the water and will therefor take longer to freeze. Aim The aim of the project is to prove whether or not adding sugar and salt to water will affect the freezing point of the water and will therefor take longer to freeze. Variables Independent Variables: the independent variables are the amount…

Discussion Leaf number, leaf area, plant height and plant spread: The effects of different levels of water stress on the growth parameters like leaf number, leaf area, plant height and plant spread of S. aethiopicum was recorded maximum in the plants grown at 100% PC. Treatments T1 and T2 (75% PC and 50% PC) did not show the significant difference, though there was drastic reduction in growth at 25% PC. Highest recording of all the parameters in 100% PC probably attributed to the optimum supply…

The proximate composition of purple soymilk (Table 1) is not much different from that of yellow soymilk. Purple soymilk has protein, ash, fat, carbohydrate and moisture content 2.76 ± 0.13, 0.12 ± 0.08, 1.17 ± 0.06, 1.27 ± 0.10, and 94.69 ± 0.04% respectively, while yellow soymilk from Tunde-Akintunde and Souley [35] has a protein content of 2.23-3.05%, ash content of 0.24-0.32%, fat content of 1.60-1.94%, carbohydrate content of 1.99-2.78% and moisture content of 92.02-93.29%. Black soybean…

The results of the lab show the decomposition rate of H2O2 at various amounts of KI, H2O, and H2O2. In addition, the effect of temperature on the rate of the reaction can also be seen in the results. Figure 1 Figure 2 `Figure 3 Figures 1,2 and 3 represent the results obtained from the keeping the amount of KI constant and varying the amount of H2O2 and water. It can be seen that when H2O2 is doubled (Figure 1 to Figure 2) the rate is also doubled from 0.0368 mL/s to 0.0723 mL/s. When the…

increased, the rate of the reaction increased as well (Francois, 1988). When speaking of reaction rates, it was also important to look into the affect that catalysts have on the reaction rate (Berkson, 1937). Such catalysts may be in the form of enzymes, which are proteins that are made up of amino acids (Brain, 2000). This piece of information is important when considering the chemical properties of gelatin, one of the main ingredients of Jell-O. Gelatin, too, is a protein made up of amino…

The rheology characteristics of enzyme clarified beetroot juice with added additives such as maltodextrin (MD), inulin (INU) and their combination (MD+INU) was studied at a wide range of concentrations (0 to 20% dry solids) and temperatures (5 to 80°C) by controlled stress rheometer. The rheological parameter shear stress was measured upto the shear rate of 600s-1. The temperature dependency of Newtonian viscosity of beetroot juice was described by Arrhenius equation. The effect of added solid…
