What is protein denaturation, what are its causes?

Protein denaturation – destruction of its structure. A protein can have a primary, secondary, tertiary and quaternary structure, which manifests itself as a change in the amino acid chain in space. The transition of the structure towards the primary is called denaturation. In this case, the structure of the protein is simplified, and it cannot perform its functions. This can be caused by high or low temperatures, chemicals such as acids and alcohols, or radiation. Any factor can destroy the quaternary structure of the protein.
