What is protein denaturation? In what sequence is the destruction of protein structures during denaturation? What is renaturation?

A change in the structure and loss of its natural properties and structure by a protein under the influence of any factors is called denatured fever. First, a weak hydrogen bond is destroyed in the Quaternary stage of the protein, then it goes into the tertiary (has the shape of a globule), then into the binary (spiral molecule with hydrogen bonds) and finally into the primary (just a chain with very strong peptide bonds).
The reverse process of denaturation is called renaturation. Protein recovery can only be observed if the changes did not affect its primary structure.
