WebD. Quaternary (4°) Structure: It is the fourth level of structural organization exhibited only in oligomeric proteins. A protein’s quaternary structure refers to the spatial arrangement of its polypeptide subunits or protomers. In a 4° structure the subunits may or may not be identical, and stabilized by non covalent bonds, e.g., Haemoglobin.
