ERYTHROCYTE CATALASE ACTIVITY IN EVER-SMOKERS AND NO-SMOKERS HEALTHY SUBJECTS: INFLUENCE OF FLAVONOIDS (QUERCETIN AND LUTEOLIN)
2013
ERYTHROCYTE CATALASE ACTIVITY IN EVER-SMOKERS AND NO-SMOKERS HEALTHY SUBJECTS: INFLUENCE OF FLAVONOIDS(QUERCETIN AND LUTEOLIN) Background. Oxygen free radicals are highly reactive species that can cause cell damage including lipid peroxidation, enzyme inactivation and DNA damage. Inactivation and removal of highly reactive species depend by the antioxidant defence systems. The catalase (CAT) belongs to the primary antioxidant defence system of the cell which catalyses the decomposition of hydrogen peroxide to water and molecular oxygen. Flavonoids are a group of polyphenolic compounds with different chemical structure and properties. They are widely distributed in fruits, vegetables, nuts, …
