Vitamin C Szent-Györgyi was awarded the 1937 Nobel Prize in Medicine, and Haworth shared that year's Nobel Prize in Chemistry. In 1957, J.J. 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
Future of the Indian Navy a builder's navy. All 41 ships under construction are being produced in Indian shipyards, both publicly and privately owned. However some projects have suffered from long delays and cost overruns. Increasing Chinese People's Liberation Army Navy interest in the Indian Ocean region has led the Indian Navy to invest more in anti-submarine ships, such as the "Kamorta"-class corvette, long-range maritime reconnaissance aircraft, and ships such as the "Saryu"-class patrol vessel and unmanned aerial vehicles such as the IAI Heron-1.
