ABSTRACT

Peptide self-assembly is a fast growing research area because self-assembly of proteins and glycolipids control the efciency of biological processes in intracellular organelles and membranes. Peptides may be considered as structural precursors for more complex protein assemblies and they present self-assembly behaviors atequilibrium, even in solute-buffer simple solutions, that is, at thermodynamic equilibrium in pseudo-binary solutions. They share many similarities with surfactants,copolymers, and nanoparticles. For instance, peptide self-organization could be related to protein folding where different parts of the secondary structure self-assemble to form a3D arrangementand the tertiary structure of the protein, which is essential to its function. Furthermore, folded
