Carambola is a fruit grown in tropical and subtropical regions of the world. Natural antioxidants including vitamin C, carotenoids, certain phenolic substances are abundant carambola fruit. As support health by acting as nutraceutical functional food additives, they help preserve preventing oxidation processes. The various organic or inorganic substrates hydrogen peroxide peroxides terminal oxi...

This study was conducted inside the wire house of Department Biology/ College Education for Pure Science/ Mosul University agricultural season 2018- 2019 to test effect vegetative and root residues Medicago satival on chemical content antioxidant enzyme fenugreek plant Trigonella foenum- graecum L. (Iraq Indian) growth under three different levels field capacity (25, 50 75%). The experiment des...

1. Physical studies of complex-formation between cytochrome c and yeast peroxidase are consistent with kinetic predictions that these complexes participate in the catalytic activity of yeast peroxidase towards ferrocytochrome c. Enzyme-ferricytochrome c complexes have been detected both by the analytical ultracentrifuge and by column chromatography, whereas an enzyme-ferrocytochrome c complex w...

in this study, we investigated the cardioprotective effects of resveratrol. rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were deter...

in the present study, some techniques were used for soybean peroxidase (sbp) purification including: ammonium sulfate fractionation, deae sephadex anion exchange chromatography and concanavalin a sepharose 4b affinity chromatography. molecular weight of purified sbp was estimated about 44 kda by sds-page as a single polypeptide band. the optimal ph and temperature for enzyme activity were found...

The peroxidase–oxidase reaction was he first (bio)chemical to show chaotic dynamics. Here, we that the rich complex dynamics observed in a detailed model of changes dramatically with enzyme concentration.

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

Background & Aim: Rosemary (Rosmarinus officinalis L.) includes species that have high drug and nutritional values. Considering the importance of the antioxidant enzyme system as an effective factor in increasing the resistance of plants to different environmental stresses, in this research, some biochemical properties of catalase and peroxidase enzymes of rosemary pla...
