The discovery that there is a close relationship between ascorbate and glutathione dates from soon after the characterization of the chemical formulae of the two molecules (Szent-Györgyi, 1931; Hopkins and Morgan, 1936). Similarly, it has long been known that thylakoids can generate hydrogen peroxide (H2O2; Mehler, 1951). Following the discovery of superoxide and superoxide dismutase in mammali...

Degradation of the extracellular matrix (ECM) plays a critical role in the formation of tumors and metastasis and has been found to correlate with the aggressiveness of tumor growth and invasiveness of cancer. Ascorbic acid, which is known to be essential for the structural integrity of the intercellular matrix, is not produced by humans and must ...

30 This study aimed to improve the shelf life of Chinese red bayberries using vacuum impregnation. 31 Vacuum pressure of 5 kPa for 15 min, atmospheric pressure for 10 min, an impregnation temperature of 32 20 °C, alone or in combination with isotonic sucrose solution, 1% food-grade disodium stannous citrate 33 (DSC), and 2% food-grade calcium ascorbate were used for vacuum impregnation. Quality...

The paper describes modern ways for selection of anti-radical substances. Molding of such components with a carbon-based material decreases the rate of its oxidative destruction. Addition of such a component to a carbon-based material decreases the rate of its oxidative destruction. The purpose of this study is to determine the antioxidant activity of ascorbates metals (Ca, Mg, Li, Co, Fe), use...
