Enzyme catalysis and inhibition
WebAug 23, 2024 · Noncompetitive Inhibitors; Enzymes are protein catalysts, they influence the kinetics but not the thermodynamics of a reaction. Increase the rate of a chemical reaction; Do not alter the equilibrium; Figure 6.2.1: Catalyst activity. WebEnzyme inhibition refers to a decrease in enzyme-related processes, enzyme production, or enzyme activity. A number of clinically important interactions between drugs result from CYP450 inhibition. CYP450 inhibitors are different in their selectivity toward enzymes and are classified by their mechanisms of action.
