WebIn this lab experiment, a baseline activity was performed to find the absorbance of the product of a mixture of guaiacol and hydrogen peroxide, along with different concentrations of peroxidase. This enzyme was extracted from turnip roots using a pH 7 buffer. The data that was gathered was used for further investigation on the subject.
http://opportunities.alumdev.columbia.edu/turnip-peroxidase-optimal-temperature.php WebSection 36. Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy, speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce ...
