coacervate
A scientist observes a coacervate forming in a clear solution under a microscope.
Definition
Noun (Biology):
- Coacervate: A microscopic droplet or aggregate of colloidal particles, especially of proteins and other organic substances, that forms spontaneously in a liquid medium. It is considered a precursor to the development of living cells in theories of the origin of life.
Verb (rare):
- To coacervate: To gather or collect into a coacervate; to undergo the process of forming such droplets.
Usage Examples
Noun:
- The coacervate formed when the protein solution was gently heated. (A microscopic droplet of organic material appeared.)
- In the laboratory, the coacervate showed simple chemical reactions similar to those in living cells. (The droplet exhibited primitive biochemical activity.)
Verb:
- The colloidal particles began to coacervate into small droplets. (The particles gathered together into a coacervate.)
- Under the right conditions, the organic molecules coacervate spontaneously. (They form droplets without external intervention.)
Advanced Usage
- "Coacervate theory": A scientific hypothesis proposing that coacervates were the first step in the formation of protocells on early Earth.
- The coacervate theory suggests that life arose from non-living organic droplets. (The theory explains how simple molecules could organize into cell-like structures.)
Variants and Related Words
Coacervation (n): The process of forming a coacervate.
- Coacervation occurs when two oppositely charged colloids mix. (The formation of droplets through aggregation.)
Coacervated (adj): Having been formed into a coacervate.
- The coacervated droplets were visible under the microscope. (The droplets had been created through aggregation.)
Synonyms
- Aggregate: A collection of particles gathered together.
- Droplet: A small drop of liquid.
- Micelle: A similar structure formed by molecules in a liquid.
