Redoxon by Albert Szent-Györgyi that isolated vitamin C from capsicum (peppers). After the sale of the Reichstein process patent to Hoffmann-La Roche, this process became the basis of the corporation's large-scale production of vitamin C. The present-day Redoxon tablets are compounded from ascorbic acid and sodium bicarbonate. When these are added to water, they react to produce sodium ascorbate, water and carbon dioxide, thus producing an effervescence. Some versions of Redoxon contain additional nutrients. Redoxon Redoxon was the brand name of the first artificially synthesized ascorbic acid (vitamin C). Redoxon was first marketed to the general public by Hoffman-La Roche in
Vitamin C -Galactose reacts with the enzyme -galactose dehydrogenase, whereby the lactone ring opens and forms again but with between the carbonyl on C1 and hydroxyl group on the C4, resulting in -galactonolactone. -Galactonolactone then reacts with the mitochondrial flavoenzyme -galactonolactone dehydrogenase. to produce ascorbic acid. -Ascorbic acid has a negative feedback on -galactose dehydrogenase in spinach. Ascorbic acid efflux by embryo of dicots plants is a well-established mechanism of iron reduction, and a step obligatory for iron uptake. All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant
