Organic compound

Definition and meaning of Organic compound in chemistry.

An organic compound is any chemical substance containing stable carbon-hydrogen bonds, which are often combined with other elements such as oxygen, nitrogen, or sulfur.

In more detail

These compounds form the fundamental chemical basis of all known biological life and represent the vast majority of all known chemical substances on Earth. The unique chemical ability of carbon atoms to form highly stable covalent bonds with themselves allows for the creation of incredibly complex molecular chains, branched structures, and rings. Millions of organic compounds have been identified, ranging from simple hydrocarbon gases utilized as fuels to massive structural macromolecules such as proteins, carbohydrates, and nucleic acids.
