Ph wert amylase
WebThe optimum pH for the reaction of starch with amylase is pH 7. PH values lower or higher than this value will result in a slower rate of reaction. Amylase works in the range pH 3 to pH 11. PH changes affect the structure of an enzyme molecule and therefore affect its ability to bind with its substrate molecules. WebNov 10, 2024 · Amylase is a digestive enzyme predominantly secreted by the pancreas and salivary glands and found in other tissues at very small levels.
