Proteins are the complex biological molecules that do most of the work in each one of our cells. WebThe non-teleological reason why proteins take on one (or only a few) forms, is based on the energetics of how they fold. Most proteins have one highly stable tertiary structure, which is often organized around a core region of hydrophobic residues.
