The Role of Lipid Membranes

A key step in the development of life may have been the spontaneous formation of lipid membranes. Experiments have shown that simple fatty acids can naturally assemble into bubbles or vesicles, creating compartments that resemble the membranes of primitive cells. These structures can trap molecules inside, offering a protected space for chemical reactions to occur and potentially setting the stage for more complex life processes. This ability to form cell-like boundaries is considered vital in the transition from chemistry to biology.
