Table 2 Self-organization accounts for the implementation of life above the molecular level

From: The essence of life

In fact, in the living world, to be functional, the folding of single functional molecules is sometimes insufficient. The formation of molecular complexes, involving interaction between biomolecules, may be important, such as hemoglobin, ion channels, and more representatively, the ribosome. This process of complex-formation is by and large akin to the assembly of amphiphiles to form vesicles, both of which are typical cases of the so-called “self-organization”. According to the description in Wikipedia, “self-organization is a process where some form of overall order or coordination arises out of the local interactions between smaller component parts of an initially disordered system”. That is, in a more general sense, we may say that it is self-organization (not only the assembly of amphiphiles forming vesicles) that enables the implementation of life from the molecular level to the level of complex entity.
