It explains how amphiphiles aggregate in water, forming structures like micelles and liposomes, driven by thermodynamics and noncovalent interactions. The page delves into the critical micelle concentration (CMC), the hydrophobic effect, and the role of noncovalent forces.

Specialized cells, such as pancreatic exocrine cells, secrete proteins through this mechanism. It also describes the "kiss-and-run" method for neurotransmitter release and the role of endosomes in releasing exosomes, which are vital for immune function.
