Life on the Earth is based on carbon. Through the course of evolution, living organisms have learned to form and process large numbers of different carbon compounds. Carbon is the cornerstone of most biologically produced organic compounds such as proteins, carbohydrates, fats and DNA. All of these compounds contain, in addition to carbon, many other elements, including hydrogen, nitrogen and oxygen.
