The enzyme tyrosinase was successively extracted by combining a homogenate of a potato and sodium sulfate with ammonium sulfate. Tyrosinase was successfully extracted by taking advantage of solubility properties of certain proteins. A standard curve was generated indicating dopachrome absorbance values through the use of a spectrophotometer and a computer graphing program. A spectrophotometer was used to measure either the amount of light that passed through a solution (transmittance) of the amount

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

Objective: The objective of the lab is to separate the caffeine samples we are using‚ using thin layer chromatography. The solvent we are using for the separation is 3:1 mixture of Chloroform and Acetone. Principle: Thin layer chromatography (TLC) is an important technique that is useful for separating organic compounds. TLC is often used to monitor the progress of organic reactions and to check the purity of products. Separations in Thin layer chromatography involve distributing a mixture of
