In short: The journey from a polypeptide to a working protein is complex. This video explores the essential levels of protein structure and the critical process of folding.

The video examines the four levels of protein structure: primary, secondary, tertiary, and quaternary. It explains how a polypeptide must undergo specific folding to become functional.

Beyond structure, the presentation covers the role of chaperonins, also known as chaperone proteins, in the folding process, as well as the mechanisms that can cause proteins to denature.
