Enzyme substrate

Purpose: The purpose of the lab was to identify a powder based on its physical and chemical properties. Materials & Apparatus: -eye protection -well plate -pipette -small toothpick/ paper clip for stirring -6 white powders: icing sugar, cornstarch, Aspirin powder, baking powder, mystery powder -test solutions in dropper bottles: water, universal indicator, vinegar, iodine solution Safety notes: Aspirin Powder- in case of contact with skin, wash with soap and water. Universal indicator- toxic…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

10. Describe the physiological roles of the different subclasses of immunoglobulins. How do the structures of these compounds relate to the function of the different classes of immunoglobulins (50 Marks?) There are four different subclasses of immunoglobulins which are IgM, IgG, IgA and the IgE. Each subclass has its physiological role in relation to its structure. The m immunoglobulin (IgM) is the first primary subclass which is produced due to primary response of the immune system. IgM is the…

also known as a monosaccharide. Sweet corn kernels are harvested and converted into starch by using caustic soda. Typically, cornstarch is 93% to 96% glucose. Because pure corn syrup is not sweet enough for food manufacturing, food processors add Enzymes to convert glucose into fructose, which changes the molecular structure. The exact ratio of glucose to fructose depends on the manufacturing process. Researchers from Princeton University concluded that the composition is about 42% glucose,…

MATERIALS AND METHODS The first day of the independent experiment was on October 25, 2016. Mannitol Salt Agar and Phenylethanol Agar are selective media that were used to isolate M. luteus from the environmental samples. Sterile cotton swabs were used to obtain the samples from the skin, arms and dust through wiping the surface of the sample source. A handful of backyard soil was previously diluted and then 2mL of this diluted soil was transferred to a sterile test tube containing 9mL water…

Purpose: The purpose of this lab is to establish a concrete understanding of limiting reagents and percent yields. In addition, the lab should give the administrator the ability to analyze the effects of reactants on the product of a chemical reaction. Procedure: In part A of the lab, the first step in the procedure is to add 20 mL, and 25 mL of CaCl2 to two different flasks. Following this, the administrator is to add 10 mL of Na2CO3 to the flask containing 20 mL of CaCl2, and 5 mL of the…

Cream may have the potential for use as a probiotic carrier because it provides an excellent environment for probiotic bacteria, with the added advantage of having nutritional value.Fatty Acids composition in fermented synbiotic cream, containing one of the two probiotic bacteria ( Lactobacillus acidophilus, Lactobacillus casei ) and inulin (0,1.5, 3%) was evaluated during 30 days for the the15-day interval at 4±1 °C. All chemical characterization were affected by the probiotic bacteria strain…

Violet red bile agar is a selective medium used to identify lactose-fermenting coliforms. This medium is typically used to test dairy products and water. The medium contains lactose which acts as a carbohydrate source, bile salts and crystal violet that act as an inhibitory agent towards gram-positive microorganisms and neutral red is added to serve as a pH indicator, microorganisms lower the pH which results in the colonies turning red. Some of the organisms that grow on this medium are:…

The Effects the Decomposition of Hydrogen Peroxide An investigation into how the amount of oxygen is produced by changing one variable effects the decomposition of Hydrogen Peroxide in the presence of the enzyme. This shows us that when the H2O2 has reacted with the catalyst this is what it produces. There are many ways in which the amount of oxygen produced could be affected. I believe that, surface area of the chip, temperature of liquid that is reacting, the concentration of the liquid…

It is essential for pharmacists to be able to predict the theoretical rate kinetics of pharmaceutical products in order to determine its shelf life. As the shelf life is defined by (t90), which is the availability of greater or equal to 90% of the drug, it is important to discover the rate of degradation of a drug to ensure that the patients receive an adequate dose of the drug. In this experiment, the stability of the active ingredient of Aspro Clear is investigated to identify the rate of…
