Introduction: A chemical reaction involves the breaking and forming of bonds in order to create the necessary energy required to cause movement. Each reaction is catalyzed (an increase in rate because of a present catalyst) by a specific enzyme. Enzymes are able to denature proteins‚ meaning that a protein loses its original shape by uncoiling‚ giving it a random‚ unstructured shape. The pineapple plant contains bromelain which‚ because of its unique characteristics‚ keeps gelatin from thickening

Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

There are competitive and non-competitive inhibitors. Both of them slow down the reaction. Competitive inhibitors are molecules that are shaped a lot like the substrate. They bind to the active site and stop the substrate from connecting. Non-competitive inhibitors connect to the enzyme in a place that is not the active site. Causing the active site to change shape. Inhibitors and catalysts are both used in everyday life. One example of how catalysts are used in everyday life is that catalysts

SC/CHEM 3001 3.0 Experimental Chemistry II Experiment A4: Palladium Catalysis: The Suzuki Reaction Abstract In this experiment‚ the Suzuki reaction was performed using phenylboronic acid‚ p-iodophenol and Pd/C catalysis in potassium carbonate aqueous media to synthesize biphenyl-4-ol. The yield of final product was only 11.94% and the measured melting point was 170-175℃. Since the appearance of the product was significantly different from expected light tan color and the measured melting

Abstract The preparation of 7.7-dichlorobicyclo [4.1.0]heptane which is also known as 7‚7-dichloronorcarane was done by reacting cyclohexene ‚ chloroform and a base( 50% aqueous sodium hydroxide) with benzyl triethylammonium chloride. The latter being a water soluble phase transfer catalyst (PTC).reaction was performed at room temperature and was distilled at atmospheric pressure. The mechanism of action of the above mentioned PTC is described in the text along with the mechanism for the addition

Institute of Chemical Technology (ICT)‚ being a research based institute I got an opportunity to broaden my knowledge and insight of kind of work going on in catalysis. I have done my individual research project in catalysis and applied to organic transformation. The results and conclusion astonish me seeing the efficiency of the principles of catalysis. Few of which I can cite here as. • First the most important are energy conservation‚ the principle on which catalyst work is lowering of activation energy

reactant in a heterogeneous system from one phase into another phase where reaction can take place. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase unless the phase transfer catalyst is present. Phase transfer catalysis (also PTC) refers to the acceleration of the reaction by the phase transfer catalyst. Phase transfer catalysts for anion reactants are often quaternary ammonium salts. The corresponding catalysts for cations are often crown ethers. A PTC works

investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without the surface of the enzyme present. Enzymes achieve this by lowering the amount of activation energy needed for anabolic reactions
