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 B6 pyridoxal and pyridoxamine. Vitamin B was named pyridoxine to indicate its structural homology to pyridine. Vitamin B6 Vitamin B refers to a group of chemically similar compounds which can be interconverted in biological systems. Vitamin B is part of the vitamin B group of essential nutrients. Its active form, pyridoxal 5′-phosphate, serves as a coenzyme in some 100 enzyme reactions in amino acid, glucose, and lipid metabolism. All forms except pyridoxic acid and pyritinol can be interconverted. Absorbed pyridoxamine is converted to PMP by pyridoxal kinase, which is further converted to PLP by pyridoxamine-phosphate transaminase or pyridoxine 5′-phosphate oxidase which
