Ascorbic 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 کاملAscorbic acid, alcohol, and environmental chemicals.
It is apparent through the efforts of a number of investigators that ascorbic acid is involved in the metabolism and detoxification of numerous xenobiotics. Interestingly, the vitamin participates a t a variety of levels, including the important hepatic electron transport systems, i.e., cytochrome P-450 mixed function oxygenase (MFO)’-’’ and flavin-containing monooxygenase ( FMO)’2-24; protecti...
متن کاملPhoto-oxidation of ascorbic acid in leaves.
These studies were planned as an extension of previous work (Mapson, 1961a) on investigations into the possible role of ascorbic acid and its oxidized forms as electron carriers in plant respiration, and the present investigation was also carried out with this object primarily in view. The results to be described in this paper suggest that the ascorbic acid system may function as an electrontra...
متن کاملXcvi. Coupled Oxidation of Ascorbic Acid
WHEN a solution of pyridine-haemochromogen containing ascorbic acid is shaken in air, both substances undergo a coupled oxidation leading to verdohaemochromogen and dehydroascorbic acid [Karrer et al. 1933; Lemberg et al. 1938, 1, 2; cf. also Haurowitz,3 1937]. When haemoglobin and ascorbic acid are incubated in air at pH 7-2 and 380 a slower oxidation takes place giving choleglobin, a bile pig...
