Proteins have a variety of shapes and formations. Proteins can have a quaternary structure; this is the final assembly in which proteins can take. It is when at least 2 or more subunits of polypeptide chains interact with each other by forming a range of bonds such as hydrogen bond, disulphide bridges/bonds and many more. Each polypeptide chain can vary in their genes they were coded from. An example of a quaternary structure protein is haemoglobin
