  • Ethanol To Acetyldehydee Lab Report

    6. The first step in metabolism of ethanol in humans is the oxidation of ethanol to acetyldehyde by the enzyme alcohol dehydrogenase (ADH). At 298 K and pH=7.0, ethanol is incubated with ADH and the concentration of ethanol and acetyldehydee is measured over time. a. Using the results above, calculate the standard free energy change (ΔGº’) for this reaction. Explain your calculations. The standard free energy change can be expressed through the formula ΔGº’=-R(gas constant) T(temp in Kelvin) lnK’eq. K’eq is equal to the products of a reaction over the reactants of a reaction, or Products/Reactants. So, K equilibrium of this question would be 3.5 (Acetaldehyde)/6512.3 (Ethanol) because this is where equilibrium is reached. So the K’eq=5.37x10-4. So to determine the ΔGº’, -R= -1.987 cal/mol K, T=298 K, and lnK’eq=-7.53. This would make the equation= -1.987(298)ln(7.53). ΔGº’ comes out to equal ~-1195. b. After dinner and a few drinks, the concentration of ethanol in a cell is measured to be 3412 mol/L and the concentration of acetaldehyde is measured to be 1.4 mol/L. Calculate ΔG’ and explain…

  • Summary: The Benefits Of Ethanol

    the fuel source, Ethanol. Whether you support the idea or not, it’s at nearly every gas station across the state. Ethanol burns cleaner emissions, lowers gas prices, and is a renewable source of energy. But some think it’s not worth creating Ethanol because it raises food prices, it requires too much energy to create than what is being yielded, and there are better ways to save oil. The truth is, these are partially true, but they still aren’t enough to stop Ethanol production. America should…

  • Ethanol Pros And Cons

    let the technology drive its own economics. If ethanol is technically viable, it will discover its own place in the economy. When it is highly subsidized, there is no way to tell where it’s true economic strength lies. “Ethanol is propped up by more than 200 tax breaks and subsidies worth at least $5.5 billion a year” (Goodell). And unfortunately biofuel production is such a huge part of the U.S. economy that removing the financial support could cause an economic meltdown the full extent of…

  • Ethanol Vs Biodiesel Essay

    An essay about Environmental, economic and energetic costs and benefits of biodiesel and ethanol biofuels. By Jason Hill et al. The authors try to determine whether ethanol, produced from corn grain, and biodiesel, produced from soybeans provide benefits over the petroleum-based fuels they displace. To be a viable alternative to fossil fuels, a biofuel (ethanol or biodiesel) should provide a net energy gain, have superior environmental benefits, be economically competitive with fossil fuels and…

  • Ethanol Cooking In Cats Essay

    What is Ethanol Poisoning in Cats? Ethanol poisoning occurs in cats when they ingest a substance that is either an alcoholic beverage or something that produces ethanol inside the body after ingestion such as uncooked pizza or bread dough. If you think your cat has ingested ethanol, it is important to visit a veterinarian as soon as possible, because if treated early there is a good chance the cat will recover. Symptoms of Ethanol Poisoning in Cats Ethanol poisoning may cause depression of…

  • Polyylactic Acid Research Paper

    • Due to cyclic nature of production of ethanol, does not add to growing concentration of carbon dioxide in the atmosphere. • Most vehicle engines are made to use octane. • Changing of car engines would be necessary in order to use pure ethanol as fuel. • Large land requirements to produce crops for ethanol from glucose. • Expensive to produce, as a lot of energy is required in the process of production, compared to expense of obtaining petrol from non-renewable sources such as fossil fuels. •…

  • Organic Staining Research Paper

    of cells, which are acidic. Also, the dye leaves a purple color on the stained neuronal tissues. For the purpose of most of our studies, Cresyl Violet staining is used to analyze the lesion size and location in the brain of mice. This staining is important in our research because the slides need to be stained properly in order for us to get accurate results. Our research team had been noticing that the slides that were stained with CV were different shades of purple and some slides had no color…

  • Analysis Of Tris Hcl, L-Ascorbic Acid

    TRIS Hcl, NBT, NADH, Ethanol, PMS, l-ascorbic acid 1. The superoxide radicals is generated in 3 ml of TrisHCl buffer (16 mM, pH 8.0) containing 1 ml of NBT (50 μM), 1 ml NADH (78 μM) and ethanol extract of sample (25 – 50 μg). 2. The reaction was started by adding 1 ml of PMS solution (10 μM) to the mixture. 3. The reaction mixture was incubated at 25° C for 5 min, the absorbance was read at 560 nm using a spectrophotometer (Schimadzu UV-Vis 1700) against blank samples using l- ascorbic acid…

  • Yeast Fermentation: A Metabolic Process

    fermentation to produce glycerol has been known since Louis Pasteur’s era in 1858. During World War II the glycerol produced from ethanol fermentation was not enough because of its low yield, thus chemical synthesis was used. Multiple methods were created by many researchers to create a more efficient method of glycerol production. There are three processes in the production of glycerol, through aerobic, anaerobic and autotrophic…
