Oxidation systems in fruits and vegetables--their relation to the quality of preserved products.
F. Aylward,D.R. Haisman +1 more
TL;DR: This chapter summarizes the available information that is relevant to fruits and vegetables on the enzymes and, in particular, oxidizing systems, which may be important in postharvest changes; the possible relationship of some of these oxidation systems to lipid oxidation by enzymic and nonenzymic mechanisms; thermal and other factors modifying or inactivating the oxidizing enzyme systems.

Relationship between tissue lipid peroxidation and peroxidizability index after α-linolenic, eicosapentaenoic, or docosahexaenoic acid intake in rats
Morio Saito,Kazuhiro Kubo +1 more
TL;DR: In this article, the extent of dietary n-3 docosahexaenoic acid (DHA)-stimulated tissue lipid peroxidation was less than expected from the relative peroxidizability index of the total tissue lipids.

Oxidative-reductive modulation of guinea pig splenic cell guanylate cyclase activity.
TL;DR: The modulation of cyclic GMP metabolism by oxidativereductive-related processes was studied in intact guinea pig splenic cells and with respect to the activities of soluble and particulate guanylate cyclase with stable effects on cGMP steady state levels.
Journal ArticleDOI
Determination of total vitamin C in fruits by capillary zone electrophoresis
TL;DR: A simple capillary zone electrophoretic method is described for the rapid determination of ascorbic acid and dehydroascorbic acid, the physiologically active forms of vitamin C, in fruits.

Human cell dehydroascorbate reductase. Kinetic and functional properties.
TL;DR: Rates of dehydroascorbate uptake by intact human neutrophils, monocytes, lymphocytes and cultured fibroblasts were proportional to cytosol dehydroasorbate reductase activities, suggesting that dehydroASorbate reduction during dehydroASCorbate absorption by these cells may be entirely enzymatic.
