How to calculate total enzyme activity
WebThe highest activity values in both flower and leaf parts was measured in acetone extract with SC50=0.287 mg/mL and (SC50=0.163 mg/mL in ABTS test, respectively. Lowest activity values of solvent extracts were measured in hexane extracts in all tests. Phenolic compounds of the plant were identified using LC-MS/MS. Web20 dec. 2024 · For instance, consider an enzyme with Vmax = 100, Km = 1. A plot of this equation follows below: The rate of change of enzyme velocity increases as substrate concentration is decreased. This is because at lower concentrations of substrate, changes in its concentration have a larger effect on the free enzyme/substrate-bound equilibrium.
