How does ascorbic acid prevent oxidation
WebThe outstanding chemical property of ascorbic acid (vitamin C) is that it is a reducing agent. The suggestion is obvious that its physiological function may be associated with this property, and, if it is oxidized reversibly, with its behavior in an oxidation- reduction system. Web18th and 19th centuries, foods able to prevent scurvy were termed antiscorbutic, although the chemical principle was not identified. Albert Szent-Gyorgyi’s group first isolated the antiscorbutic princi-ple and named it ascorbic acid (he received the Nobel Prize in 1937).
