that substrate, as well as a test tube with the original concentration as a control group. By adding the same amount of enzymes to each of the test tubes, you can use the spectrophotometer in order to see the yellow color from test tubes due to the chemical reactions that occur. After observing each test tube, you can then determine if the test tubes containing the higher concentrations of substrate ended up with a more saturated yellow color than the original

Medicine During the Elizabethan Era The medicinal practices and problems of the Elizabethan Era were very important to the people, although they are very different from those of today. There were many different beliefs and diseases, like the Plague. Medicine was not an exact science and was related to Alchemy (Chemistry). Here, some of the many practices and beliefs of the Elizabethan Era will be discussed. One of the most widely known and important of the beliefs was the humours. It was

causes the 3 phases: solid, liquid and vapour, of a single component system to be in equilibrium. (Blackwell Scientific Publications Oxford 1997) This definition shows that sublimation is a purely physical process; so a substance does not undergo a chemical reaction during sublimation. This diagram represents a typical endothermic reaction: Fig. 2: Endothermic reaction enthalpy change (hferrier n.d.) As displayed in figure 2, a substance requires kinetic energy greater or equal to its activation

A general trend in dual ACC1/ACC2 inhibition was often encountered among the 125 compounds tested: good ACC1 inhibition was linked to good ACC2 inhibition.4 The same group elaborated on this study by examining the structure–activity relationship (SAR) for the pyrazole part and the substitution at position 9 of the 1,9-diazaspiro[5.5]- undecane. In this study, additional pharmacokinetics were studied along with the IC50 values for ACC1 and ACC2, such as the lipophilic ligand efficiency (LipE)

to a part of the system that is at elevated pressure. The sample is then transported to a separator by the flow in the system.      After the column the separated compounds enter the detector, which measures a physical or chemical property of each, now relatively pure, compound and creates a proportional electronic signal. By calibrating with a standard mixture of known compounds, the nature of the compound in the

Gulf War Syndrome The Gulf War Syndrome was identified after the Gulf War in 1991. Thousands of troops from the US, British, and Canadian developed symptoms after the war. This Syndrome has been researched since the end of the Gulf War and still not all the answers have been found. Not only have thousands of troops suffered from this syndrome, but also their families have developed some symptoms related to this syndrome. It is important to inform our nation of this new disease because there

Effects of Temperature, pH, Enzyme Concentration, and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes, proteins that act as catalysts, are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes, the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

Kinetics of Hydrogen Peroxide February 22, 2007 Chem. 1130 TA: Ms. Babcock Room 1830 Chemistry Annex PURPOSE OF THE EXPERIMENT Kinetics of Hydrogen Peroxide The major purpose of this experiment is to determine the rate law constant for the reaction of hydrogen peroxide and potassium iodide. In this experiment, the goal will be to try to measure the rate law constant at low acidity, since at low acidity, anything less than 1.0 x 10-3M, the effect of the hydrogen ion is negligible. To calculate

The Leukart reaction is 2-step with lower yields and requires chemical apparatus. There are also two synthetic methods which proceed directly from safrole rather than through isosafrole. The first is the Ritter reaction which goes through the intermediate N-acetyl-MDA. The Ritter reaction is time-consuming, requires

An enzyme is a biological catalyst. It speeds up a reaction by lowering the activation energy required to start the reaction. It speeds up a reaction, but remains unchanged unless certain limiting factors are introduced. It is composed of polymers of amino acids. An enzyme has an optimum pH and temperature. When an enzyme is at its optimum conditions, the rate of reaction is the fastest. In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of
