Direct Electrochemistry of Polyphenol Oxidase
The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
متن کاملOnion, a Potent Inhibitor of Xantine Oxidase
Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

متن کاملP-91: Vitamin E and Selenium Supplementation Affects Aldehyde Oxidase, Xanthine Dehydrogenase/Oxidase Activities In Diabetic Rat Ovaries
Background Any factor like diabetes that changes the oxidant/antioxidant balance in favor of oxidants could possibly disrupt the physiologic function of ovaries. So, we have investigated the effect of vitamin E and Se supplements on antioxidant defense in ovaries of diabetic rats with focus on Xanthine dehydrogenase/oxidase (XDH/XO) and Aldehyde oxidase (AO) activities. MaterialsAndMethods This...
متن کاملSubstrate specificities of rat liver peroxisomal acyl-CoA oxidases: palmitoyl-CoA oxidase (inducible acyl-CoA oxidase), pristanoyl-CoA oxidase (non-inducible acyl-CoA oxidase), and trihydroxycoprostanoyl-CoA oxidase.
Rat liver peroxisomes contain three acyl-CoA oxidases:palmitoyl-CoA oxidase, pristanoyl-CoA oxidase, and trihydroxycoprostanoyl-CoA oxidase. The three oxidases were separated by anion-exchange chromatography of a partially purified oxidase preparation, and the column eluate was analyzed for oxidase activity with different acyl-CoAs. Short chain mono (hexanoyl-) and dicarboxylyl (glutaryl-)-CoAs...
