Webwheat germ. Acid phosphatases have optimal activity at pH values from 4 to 6, and are distinct from alkaline phosphatases with optimal activity in the pH range of 8-9. The function of the wheat germ phosphatase has not been definitively established, but it has been proposed that it is WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution.
