From Wikipedia, the free encyclopedia

See Biological material for other meanings.

Biological matter or biological material refers to the unique, highly organized substances of which cellular life is composed of, for instance membranes, proteins, and nucleic acids. They may also be called cellular components.

Most biological matter has the characteristics of soft matter, being governed by relatively small energies.

All known life is made of biological matter. To be differentiated from other theoretical or fictional life forms, suchlife may be called carbon-based, cellular, organic, biological, or even simply living—as some definitions of life exclude alternative biochemistry.
