P. Stonebraker Organic Chemistry II lecture UCB Extension Spring 2013 Extra Credit Report Papers Paper is strictly optional. Write a 4-6 page paper on a subject approved by the instructor (either picked from the list below or picked by yourself). Emphasis in the paper should be on the organic chemistry associated with the subject (how it is synthesized‚ uses‚ etc.). No two students can research the same subject. Maximum value of the paper will likely in the 20-40 point range‚ depending

Enzyme are a very important component in living organisms. If enzymes did not exist than life itself would not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not

Agents Of Spoilage 1.Microorganism A microorganism (from the Greek: μικρός‚ mikros‚ "small" and ὀργανισμός‚ organismós‚ "organism") or microbe is a microscopic organism‚ which may be a single cell[1] or multicellular organism. The study of microorganisms is called microbiology‚ a subject that began with Antonie van Leeuwenhoek’s discovery of microorganisms in 1675‚ using a microscope of his own design. On 8 November 2013‚ scientists reported the discovery of what may be the earliest signs of life

only the pathways giving significant yields of the desired product have been listed below. i. Suzuki Coupling of aryl chlorides with aryl boronic acids (Myung-Jong Jin and Dong-Hwan Lee‚ 2010) Suzuki coupling reaction is an example of heterogeneous catalysis. The advantage of heterogeneous catalytic systems is that they can be considerably re-used whilst keeping the inherent activity of the catalytic centre. Aryl bromides and iodides are widely employed in heterogeneous coupling reactions. But from a

CHEMICAL KINETICS RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant

manufacturing processes are often designed relying on empiricism‚ leading to uncertain/suboptimal processes‚ decreased quality‚ and increased cost. By combining the substantial level of expertise in particle technology‚ optimization‚ multi-scale simulation‚ catalysis and molecular modeling available at Rutgers‚ we are developing and promoting science-based methods for designing and optimizing catalyst manufacturing methods and processes such as impregnation‚ drying‚ slurry mixing‚ extrusion‚ calcination‚ etc

Conclusion This lab was helpful in showing us how enzyme catalysis really happens in biology. These series of experiments have proven what the optimal conditions and which are not conducive to the functioning of Peroxidase. Table 7.1 was the trial experiment and was performed to observe the overall activity of the enzyme Peroxidase. Each of the three tube mixtures were filled with different concentrations of Peroxidase. As seen on the chart the mixture of tube six and seven had the fastest

globular proteins and are around 62 amino acids residues in size. What enzymes do is determined by their 2-dimensional shape. A lot of enzymes are bigger than the substrate they act on‚ but only a little part of the enzyme involved directly with the catalysis. Without enzymes the chemical reactions in the body‚ would be so slow‚ the body would shut down. And cell reactions would take too much energy that our body won’t be able to provide. Like a wrench that stays the same
