WebThis pH range is slightly basic and is similar to the pH of human saliva, which is why amylase is active in the mouth during the process of digestion. At pH values outside of this optimal range, the activity of alpha-amylase decreases significantly. Beta-amylase has an optimal pH range of 4.5 to 5.5, with the highest activity at pH 5.0. WebJul 1, 2001 · The activity as a function of pH was measured over the range pH 4.0–10.5, using the Phadebas α-amylase test kit (Pharmacia). Measurements were carried out in duplicate at 30°C in 50 mM Britton–Robinson buffer (50 mM H 3 PO 4 + 50 mM CH 3 COOH + 50 mM H 3 BO 3) containing 0.1 mM CaCl 2.
