The denaturation (unfolding) and renaturation (refolding) of a protein is depicted. The red boxes represent stabilizing interactions, such as disulfide linkages, hydrogen bonding, and/or ionic bonds. The primary structures of proteins are quite sturdy.
Denaturation, in biology, process modifying the molecular structure of a protein. Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural state.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiatio...
What is Denaturation of Proteins? Denaturation implies the destruction of the tertiary structure of a protein molecule and the formation of random polypeptide chains. Denaturation of proteins is one of the phenomenons that results in the disturbance of stability and structure of the protein.
Denaturation is the process of breaking many of the weak bonds, such as hydrogen bonds, that give proteins their highly ordered structure when they are in their native, natural state. Weak and irregularly arranged, denatured proteins are mostly insoluble.
When a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denaturation of the proteins of egg white by heat—as when boiling an egg—is an example of irreversible denaturation.
Denaturation is the term used for any change in the three-dimensional structure of a protein that renders it incapable of performing its assigned function. A denatured protein cannot do its job because there is a change in the secondary, tertiary, or quaternary structure.
Key Terms. chaperonin: proteins that provide favorable conditions for the correct folding of other proteins, thus preventing aggregation. denaturation: the change of folding structure of a protein (and thus of physical properties) caused by heating, changes in pH, or exposure to certain chemicals.

denaturation: the change of folding structure of a protein (and thus of physical properties) caused by heating, changes in pH, or exposure to certain chemicals; Each protein has its own unique sequence of amino acids and the interactions between these amino acids create a specify shape.
