WebFeb 14, 2024 · Denaturation. Loss of the secondary, tertiary, and quaternary structures of proteins by a physical process or a chemical agent, while maintaining the primary structure almost intact, is called denaturation of proteins. Proteins unfold and become almost linear polypeptide chains upon denaturation. Denatured proteins can not perform their functions. WebTo understand misfolded proteins or prion-proteins, let’s first understand what normal proteins are. Proteins are linear chains composed of building blocks called amino acids.
