The Effect Of pH On Invertase Activity Introduction Invertase Sucrose+water glucose + fructose Invertase is an enzyme which is usually found in plants. It acts as a catalyst for the hydrolysis of sucrose. (Campbell&Reece,2002) Sucrose is a disaccharide composed of glucose and fructose linked by a glycosidic bond. When this bond is cleaved in a hydrolysis reaction, an equal amount of glucose and fructose. Invertase is a significant enzyme because glucose is an important product of photosynthesis. Invertase is also used in the confectionery industry where fructose is preferred over sucrose because it is sweeter and does not crystallize easily. The reaction is shown as follow: Enzymes are affected by changes in pH. (Campbell & Reece, 2002) Extreme pH values generally result in loss of activity for most enzymes. Furthermore, there is a most favorable pH for enzyme - the point where the enzyme is most active. This point is known as the optimal...
