Optimum ph for amylase enzyme
Web4.1 Effect of pH on the activity of amylase Effect of pH on alpha amylase purified from Malus pumila was determined by assaying enzyme at different pH ranging from 1-10 and amylase showed a pH optimum of 6.8 (Kanwal et. al., 2004) [15]. Similarly Gouda and Elbahloul (2008) [11] determined the effect of pH on amylase produced by halotolerent ... WebAug 16, 2024 · The median value of this pH range is called the optimum pH of the enzyme (part (b) of Figure 18.7. 2 ). With the notable exception of gastric juice (the fluids secreted in the stomach), most body fluids have pH values between 6 and 8. Not surprisingly, most enzymes exhibit optimal activity in this pH range.
