Coacervates (/koʊəˈsɜːrvəts/ or /koʊˈæsərveɪts/) are organic-rich droplets formed via liquid-liquid phase separation, mainly resulting from association of oppositely charged molecules (macro-ions, polyelectrolytes, polysaccharides, proteins, etc.)[1] or from hydrophobic molecules/proteins[clarification needed] (such as elastin-like polypeptides).[2] Coacervation is a phenomenon that produces coacervate colloidal droplets.
