In this video, we explore the final two levels of protein structure. These are called the tertiary structure and the quaternary structure. We start by looking at what is meant by tertiary structure and why it is so important to the functioning of a protein. We then explore the idea of quaternary structure, including what is meant by a prosthetic group and a conjugated protein.
