Phospholipid Membranes

Phospholipid membranes, essential to all known cells, spontaneously form spherical structures called vesicles in water due to their unique hydrophobic and hydrophilic properties. This self-organization occurs in environments like hydrothermal vents, creating a protective barrier that concentrates organic molecules, a crucial step in the origins of life. The ability of these molecules to arrange themselves into membranes illustrates the fundamental processes that underpin cellular life.
