Add a definition Assessment of these data prompted two experiments to determine whether endogenous factors in blood and plasma from women with preeclampsia escalate oxidative depletion ofascorbatein vitro. From theCambridge English Corpus Plasmaascorbatecompletely protects plasma lipoproteins from peroxidation during exposure to a wide spectrum of water- or lipid-soluble free radical generators in vitro. From theCambridge English Corpus In the present study, we have focused on the relationship between desiccation sensitivity and activities of free radical-scavenging enzymes (ascorbateperoxidase, peroxidase and superoxide dismutase) in seeds. From theCambridge English Corpus Ascorbateperoxidase activity increased during this process but declined when the leaf was desiccated. From theCambridge English Corpus Tocopherol was extracted by grinding seed tissue in ice-cold 2:1 hexane:aqueousascorbate(10% w/v). From theCambridge English Corpus The pecking order of free radicals and antioxidants: lipid peroxidation, a-tocopherol andascorbate. From theCambridge English Corpus However,ascorbateperoxidase activity was very low and did not change, whereas peroxidase activity decreased steadily during desiccation. From theCambridge English Corpus Ascorbateacts at the water-lipid interface to recycle tocopherol radical and thus inhibit the chain of lipid peroxidation. From theCambridge English Corpus During its antioxidant action,ascorbateundergoes two consecutive one electron oxidations to dehydroascorbic acid with intermediate formation of the ascorbate radical. From theCambridge English Corpus The initialascorbateradical signal amplitude is directly proportional to the overall rate of ascorbate oxidation, whereas the signal duration is inversely proportional. From theCambridge English Corpus Strikingly, exogenously appliedascorbate, a predominantly neuronal antioxidant, could compensate for the loss of any other single component of the antioxidant network. From theCambridge English Corpus The sodiumascorbatesolution was prepared just prior to use. From theCambridge English Corpus However, in the cotyledons, noascorbateperoxidase activity was detected at any water content, and peroxidase activity was gradually reduced as desiccation proceeded. From theCambridge English Corpus We hypothesize thatascorbateis an integral component of the photoreceptorsynaptic release mechanism. From theCambridge English Corpus These data demonstrate than anascorbate-oxidizing activity is increased in plasma from women with preeclampsia. From theCambridge English Corpus Consequently, cellular regulation ofascorbateis speciesindependent, so that whether an animal can synthesize ascorbate should not influence other components of the antioxidant network. From theCambridge English Corpus In addition,ascorbate(0.5%) was routinely added to reduce the oxidation of the released catecholamines. From theCambridge English Corpus This action ofascorbatewould occur regardless of the presence or absence of retinal dopamine and would thereby constitute the normal response to a flash. From theCambridge English Corpus These critical water contents corresponded to water contents below which activities of free radicalscavenging enzymes (ascorbateperoxidase, peroxidase and superoxide dismutase) decreased rapidly during desiccation. From theCambridge English Corpus It is possible thatascorbate, present in follicular fluid, induces taurine and hypotaurine accumulation in rabbit oviduct fluid at the time of ovulation.
