What does the term "organic" refer to in scientific contexts?

In scientific contexts, the term "organic" refers to substances that are primarily derived from living organisms or contain carbon-based compounds. This classification typically encompasses a wide range of materials, including proteins, lipids, carbohydrates, and nucleic acids, all of which are fundamental components of life. Organic compounds are characterized by their complex structures and the presence of carbon-hydrogen bonds, which are essential for the formation and function of biological molecules.

The notion that "organic" indicates a relationship with living things is foundational in various fields, such as chemistry, biology, and environmental science. Organic chemistry, for instance, is the branch that focuses on the study of carbon-containing compounds and their properties, reactions, and structures, which are often derived from or related to organisms. This understanding of "organic" as linked with life forms is integral to exploring broader topics within biology and ecological studies, where the impact of organic materials on ecosystems and living organisms is significant.
