Introduction The aim of this experiment is to see the effect of different Pectinase concentrations have on the production on apple juice. Pectinase is an enzyme‚ which breaks down pectin‚ a polysaccharide found in plant cell walls. This enzyme is mainly commercially used to speed up the process of fruit juice production as the cell walls of plants are broken down more quickly. Therefore by changing the Pectinase concentrations‚ the results may show the effects it may have on how much apple juice

The Behavior of Proteins: Enzymes Enzymes are Effective Biological Catalyst Catalysis- speeds up metabolism to allow production of products. Enzymes- Highly specific and most efficient catalyst that speeds up metabolism or rate of reaction in organisms by factor up to 10^20 (globular proteins) Nonenzymatic catalyst- enhance by 10^2 -10^4 Ribozymes- acts for catalytic activity in RNA’s Kinetics versus Thermodynamics Standard free energy change- difference between the energies of the reactants

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

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

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

Asymmetric Catalysis in Intramolecular Reactions of α-Diazoketones. Abstract: Carbon-hydrogen insertion reactions involve the insertion of a carbene‚ a neutral carbon atom or molecule with two unpaired valence electrons‚ into an unactivated carbon-hydrogen bond. This reaction produces many commercially valuable compounds. The reaction itself involves the use of diazocarbonyl compounds which contain an N2 ligand on a carbon alpha to a carbonyl. The reaction is thermodynamically favourable as it involves

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

characterized using three methods which are the infrared spectra‚ X-ray diffraction as well as the TGA and DTA methods. 2.0 Introduction Catalyst is a substance that causes the change in rate of a chemical reaction. This reaction is known as catalysis and unlike other reagents that take part in a chemical reaction catalyst can be reused again as it will not be consumed by the reaction. Catalyst functions by offering a pathway for a reaction with a lower activation‚ therefore allowing for an increased

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply
