Unformatted text preview: Organic Molecules Organic compounds are those that have carbon atoms. In living systems, large organic molecules, called macromolecules, can consist of hundreds or thousands of atoms. Most macromolecules are polymers, molecules that consist of a single unit (monomer) repeated many times. Four of carbon's six electrons are available to form bonds with other atoms. Thus, you will always see four lines connecting a carbon atom to other atoms, each line representing a pair of shared electrons (one electron from carbon and one from another atom). Complex molecules can be formed by stringing carbon atoms together in a straight line or by connecting carbons together to form rings. The presence of nitrogen, oxygen, and other atoms adds variety to these carbon molecules. Four important classes of organic molecules—carbohydrates, lipids, proteins, and nucleic acids—are...
