Vitamin C beings. According to this theory, the loss of ascorbic acid's anti-oxidizing properties would have led to an increase in free radicals in the body. Free radicals are known to increase the frequency of genetic mutations, which would subsequently increase the speed of evolution. It has also been noted that the loss of the ability to synthesize ascorbate strikingly parallels the inability to break down uric acid, also a characteristic of primates. Uric acid and ascorbate are both strong reducing agents. This has led to the suggestion that, in higher primates, uric acid has taken over some of the functions of
Chemistry of ascorbic acid acid solution. Electrolyzing the solution of potassium iodide produces iodine, which reacts with ascorbic acid. The end of process is determined by potentiometric titration in a manner similar to Karl Fischer titration. The amount of ascorbic acid can be calculated by Faraday's law. Another alternative uses "N"-bromosuccinimide (NBS) as the oxidizing agent, in the presence of potassium iodide and starch. The NBS first oxidizes the ascorbic acid; when the latter is exhausted, the NBS liberates the iodine from the potassium iodide, which then forms the blue-black complex with starch. Chemistry of ascorbic acid Ascorbic acid is an organic compound with
