Ph of maltase
WebThe optimum pH of alpha-amylase is 6.7–7.0. Ptyalin is mixed with food in the mouth, where it acts upon starches. Although the food remains in the mouth for only a short time, the action of ptyalin continues for up to several hours in the stomach—until the food is mixed with the stomach secretions, the high acidity of which inactivates ...

WebJul 29, 2002 · pH pH is defined as the negative log 10 of the hydrogen ion concentration. Although this definition is intended to assist the scientist by allowing one to express very small quantities without the use of cumbersome fractions (e.g. 0.000000001 gm / liter), students often have difficulty because of two things. simplified triangulationWebMaltase from B. licheniformis KIBGE-IB4 was characterized in term of its catalytic properties.
