Abstract
Objective: In uncontrolled diabetes mellitus, concentration of ketone bodies is elevated to up to 25mM. This study aims to investigate the inhibitory action of ketone bodies on paraoxonase and arylesterase activity of Paraoxonase1. Method: The inhibition of Paraoxonase1 by ketone bodies was determined spectrophotometrically by using paraoxon and phenyl acetate as substrates. Result: Acetone decreased 32% of paraoxonase activity and 23% of arylesterase activity. Sodium-3-hydroxybutyrate showed 20% reduction in paraoxonase activity but it did not affect arylesterase activity. In contrast, neither of the enzyme activities was affected by sodium-acetoacetate. Conclusion: Higher concentration of acetone and sodium-3- hydroxybutyrate contribute to the reduction of Paraoxonase1 activity.
