This experiment revolves around isolation of Polyphenol Oxidase (PPO) and the determination of this enzyme’s optimal pH and temperature. Polyphenol Oxidase (PPO) is an enzyme that catalyses the oxidation of phenols to quinones upon exposure to oxygen. The quinones are converted to dark pigments (black, brown or red) which results in enzymatic discolouration thereby leading to browning of plant materials...
