Life is based on carbon's ability to bond with other carbon atoms to form diverse structures. The study of structure, properties, and reactions of compounds that contain carbon is what organic chemistry is all about. The term organic is derived from organisms and as of now, more than 13 million organic compounds are known and 100,000 continue to be added to the list every year. Some of the compounds are discovered in nature while others are synthesized in a laboratory. It is this ability to create new compounds that make organic chemistry so exciting.
Some of the areas where organic molecules play a key part beyond human body i.e. DNA, proteins, lipid, peptides, enzymes and nucleic acids are discussed next.
