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 time it was shown that not all vitamins are amines, the word was already ubiquitous. In 1920, Jack Cecil Drummond proposed that the final "e" be dropped to deemphasize the "amine" reference, after researchers began to suspect that not all "vitamines" (in particular, vitamin A) have an amine component. In 1930, Paul Karrer elucidated the correct structure for beta-carotene, the main precursor of vitamin A, and identified other carotenoids. Karrer and Norman Haworth confirmed Albert Szent-Györgyi's discovery of ascorbic acid and made significant contributions to the chemistry of flavins, which led to the identification of lactoflavin.
