1 Nevertheless, while TAML/H2O2 rapidly degrades the drug propranolol, a micropollutant (MP) of broad concern, propranolol is shown to inhibit its own destruction under concentration conditions amenable to kinetics studies ([propranolol] = 50 muM). Propranolol latexin Homo sapiens

3 However, based on the measured kI and calculated equilibrium constant K for propranolol-TAML binding, it is possible to project the impact on kI of reducing [propranolol] from 50 muM to the ultradilute regime typical of MP contaminated waters (<=2 ppb, <=7 nM for propranolol) where inhibition nearly vanishes. Propranolol latexin Homo sapiens

6 Projecting from 50 muM to higher concentrations, propranolol completely inhibits its own oxidation before reaching mM concentrations. Propranolol latexin Homo sapiens
