Burns showed that some mammals are susceptible to scurvy as their liver does not produce the enzyme -gulonolactone oxidase, the last of the chain of four enzymes that synthesize vitamin C. American biochemist Irwin Stone was the first to exploit vitamin C for its food preservative properties. He later developed the theory that humans possess a mutated form of the -gulonolactone oxidase coding gene. In 2008, researchers at the University of Montpellier discovered that in humans and other primates
