Entropy-Driven Amino Acid-Based Coacervates with Enzyme-Free Metabolism and Prebiotic Robustness

Protocells capable of nonenzymatic metabolism and environmental adaptation are essential models for understanding the emergence of cellular life. However, existing protocell designs often lack the robustness or prebiotic relevance to explain how functional supramolecular assemblies could have formed...
