Synthesis of L

In plants L-ascorbic acid (AsA) is essential for photosynthetic activity via the detoxification of superoxide and hydrogen peroxide in chloroplasts in the absence of catalase [] AsA is also crucially involved in the regeneration of α-tocopherol and zeaxanthin and the pH-mediated modulation of PS II activity [] The critical importance of AsA in photosynthetic metabolism is emphasised by its

Total Glutathione Assay

The OxiSelect™ Total Glutathione Assay Kit is a quantitative assay for measuring the total glutathione content within a sample (GSH/GSSG) Glutathione Reductase reduces oxidized glutathione (GSSG) to reduced glutathione (GSH) in the presence of NADPH Subsequently the chromogen reacts with the thiol group of GSH to produce a colored compound that absorbs at 405 nm
