WebbAnswer (1 of 3): We often think of proteins consisting of a single polypeptide chain, and this is true for many proteins, like lysozyme or myoglobin. However for many other proteins, the functional unit consists of multiple polypeptide chains, and these are called subunits. They can be all the sa... In structural biology, a protein subunit is a polypeptide chain or single protein molecule that assembles (or "coassembles") with others to form a protein complex. Large assemblies of proteins such as viruses often use a small number of types of protein subunits as building blocks.
