The diverse nature of oligomers. Oligomeric assemblies ranging from two to six monomers. Each sphere represents a monomeric unit. Monomers (grey), dimers (red, diagonal lines) and trimers (white) can combine in different combinations comprising up to six monomers. Each small oligomer also could be a building block for larger oligomers. For simplicity and clarity, we only display basic units up to trimer. We note that the assemblies shown here, and others, are in rapid equilibrium, one that can be perturbed easily during experimental studies.
