, 2012 The reduction of dehydroascorbate (DHA) to ascorbic acid (AA) is a vital cellular function. The omega-class glutathione transferases (GSTs) catalyze several reductive reactions in cellular biochemistry, including DHA reduction.

Short- and long-term effects of dehydroascorbate in Lupinus albus and Allium cepa roots
, 2001 Administration of 1 mM dehydroascorbate (DHA) results in a rapid and large increase in cellular ascorbate (AA) content in both Lupinus albus L. and Allium cepa L. root tips. Uptake of DHA from the medium occurs at a high rate within 10-12 h of incubation,

Antioxidants and Manganese Deficiency in Needles of Norway Spruce (Picea abies L.) Trees
, 1992 Chlorotic and green needles from Norway spruce (Picea abies L.) trees were sampled in the Calcareous Bavarian Alps in winter. The needles were used for analysis of the mineral and pigment contents, the levels of antioxidants (ascorbate, glutathione), and

ENZYMATIC RECYCLING OF OXIDIZED ASCORBATE IN PIG-HEART - ONE-ELECTRON VS 2-ELECTRON PATHWAY
, 1991 Enzymatic systems able to reduce either dehydroascorbate or ascorbyl radical back to ascorbate by "recycling" vitamin C may contribute to lowering the nutritional requirement of it and to increase tissue antioxidant capacity.

New insights into the dynamics of the glutathione-ascorbate redox system of plants
Journal of Applied Botany and Food Quality, 2012 The Hallilwell-Asada-Foyer redox cascade (HAF) is viewed as a H2O2 detoxifying system with a great variety of responses against environmental changes. The functional consequences of these responses are interpreted intuitively because a systemic analysis ...
