- Coacervates, or biomolecular condensates, are liquid droplets found in cells that perform crucial functions, and their malfunction may contribute to diseases like Alzheimer's and cancer.
- These droplets were first studied in the early 20th century and proposed by Alexander Oparin in the 1930s as key to the origins of life, acting as simple precursors to cells in the primordial soup.
- Research since 2009 has confirmed their ubiquity and importance in modern cells, such as in the nucleolus for ribosome production, and they can form spontaneously from simple molecules like short peptides.
- Coacervates can concentrate chemicals, drive reactions (e.g., protein formation), and exhibit lifelike behaviors such as growth and division, making them integral to theories about how life began.
- Studies show coacervates can develop internal compartments or membranes, and ongoing research aims to integrate genetic or metabolic systems within them to better understand early life processes.
