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. WebProtein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases.
