* Organic chemistry is the study of compounds containing carbon, with the exception of a few simple molecules like carbon dioxide and carbonates.
* Proteins are large, complex molecules made up of long chains of amino acids.
* Amino acids themselves contain carbon atoms, along with hydrogen, oxygen, and nitrogen.
Therefore, the presence of carbon in the structure of proteins makes them fit the definition of organic compounds.
Additionally, proteins, like many other organic molecules, are involved in complex biological processes and are essential for life.
