Ascorbic acid monoglucoside as antioxidant and radioprotector.
Ascorbic acid monoglucoside (AsAG), a glucoside derivative of ascorbic acid, has been examined for its antioxidant and radioprotective abilities. AsAG neutralized 1, 1 diphenyl -2-picryl-hydrazyl (DPPH), a stable free radical in a concentration dependent manner thus indicating its antioxidant ability. AsAG protected mice liver tissues in vitro from peroxidative damage in lipids (measured as TBA...
متن کاملAscorbic acid and copper in linoleate oxidation. II. Ascorbic acid and copper as oxidation catalysts.
Both ascorbic acid and copper were strong prooxidants in the oxidation of linoleate in a buffered (pH 7.0) aqueous dispersion at 37 degrees C. Minimum concentrations at which catalytic activity was detected were 1.3 x 10(-7) m for copper and 1.8 x 10(-6) m for ascorbic acid. For concentrations up to 10(-3) m, the increase in rate of oxidation with increase in concentration of catalyst was great...
متن کاملAscorbic acid and copper in linoleate oxidation. 11. Ascorbic acid and copper as oxidation catalysts
Both ascorbic acid and copper were strong prooxidants in the oxidation of linoleate in a buffered (pH 7.0) aqueous dispersion at 37OC. Minimum concentrations at which catalytic activity was detected were 1.3 X 10-7 M for coppcr and 1.8 X 10-6 M for ascorbic acid. For concentrations up to lop3 M, the increase in rate of oxidation with increase in concentration of catalyst was greater for ascorbi...
متن کاملIs ascorbic acid an antioxidant for the plasma membrane?
Ascorbic acid, or vitamin C, is a primary antioxidant in plasma and within cells, but it can also interact with the plasma membrane by donating electrons to the alpha-tocopheroxyl radical and a trans-plasma membrane oxidoreductase activity. Ascorbate-derived reducing capacity is thus transmitted both into and across the plasma membrane. Recycling of alpha-tocopherol by ascorbate helps to protec...
متن کاملStronger antioxidant enzyme immunoreactivity of Populus tomentiglandulosa extract than ascorbic acid in rat liver and kidney
Objective(s): Populus species have various pharmacological properties, including antioxidant activity. In this study, the effects of Populus tomentiglandulosa extract (PTE) on histopathology and antioxidant enzymes in the rat liver and kidney were examined. Materials and Methods: Sprague-Dawley rats were assigned to three groups; (1) no...
