- Title
OXIDIZING EFFECTS OF ACIDIFIED OXYHAEMOGLOBIN SOLUTIONS.
- Authors
Lemberg, R.
- Abstract
When a solution of oxyhaemoglobin containing ascorbic acid is acidified, ascorbic acid is destroyed. This destruction is largely due to direct oxidation by active oxygen and is no longer found when the ascorbic acid is added after acidification. Biliverdin is also oxidized by acidified oxyhaemoglobin, but is still oxidized when added after acidification. This oxidation is due to hydrogen peroxide formed by the action of active oxygen on the globin, with acid haematin acting as peroxiadative catalyst.
