WebMost insect amylases have molecular weights in the range 48–60 kDa, pI values of 3.5–4.0, and Km values with soluble starch around 0.1%. pH optima generally correspond to the pH prevailing in midguts from which the amylases were isolated. 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. chuck e is love lyrics
