Renatured proteins have the same overall 3D structure as their native form, while denatured proteins have lost their original structure due to disruptions in non-covalent interactions like hydrogen bonds and van der Waals forces. Denatured proteins may be unfolded or adopt a misfolded structure, while renatured proteins correctly refold back to their native state.

Proteins cannot be denatured by?
Proteins cannot be denatured by freezing, as this process can stabilize proteins and prevent denaturation.
How are molecules such as proteins denatured?
Most commonly a protein can be denatured due to several factors. One of the most common ways of denaturing proteins is through heat. Proteins can also be denatured by exposure to alcohol.
If protein is denatured by heat does it continue to denature after heat is removed?
No, once heat is removed and the protein cools down, it will not continue to denature. The denaturation process is irreversible, so the protein structure will not return to its original state once it has been heated.
What is meant by the term denatured?
Denatured refers to when a protein loses its structure to become something akin to an amorphous blob. To really understand this though you must understand the structures of protein. A protein is a long string or chain composed of amino acids all linked together. When proteins are formed by the body they must 'fold' themselves into a structure that is capable of work or doing a task. Once in this folded form the protein can go on to serve whatever function it serves. Denaturing causes the protein to lose this shape and ultimately functionality. For the most part denatured proteins can be 'renatured' by reversing the cause of denaturing. A familiar example of denaturing while is non reversible is cooking eggs. The egg white is rich in proteins and when heated causes the protein to lose it's form and harden. As stated this can't be reversed.
Can proteins be denatured or coagulated by heat or acidity?
Yes, proteins can be denatured (change in structure) by heat or acidity, leading to loss of their functional properties. Denaturation disrupts the bonds holding the protein's shape, altering its structure. Coagulation refers to the aggregation of denatured proteins, forming clumps, which can happen under extreme heat or acidity conditions.

What is renaturation?
Renaturation is the process of restoring the natural state or structure of a biological molecule, such as DNA or proteins, after it has been denatured. This can involve reversing the effects of denaturation by allowing the molecule to refold back into its original functional conformation.
Do denatured proteins have their shape changed?
Denatured proteins do not have any particular shape. A denatured protein is one that has broken amino acid interactions in the secondary and tertiary structures.
If protein is denatured by heat does it continue to denature after heat is removed?
No, once heat is removed and the protein cools down, it will not continue to denature. The denaturation process is irreversible, so the protein structure will not return to its original state once it has been heated.
Do denatured proteins have nutritional value?
yes
Can proteins be be denatured or coagulated by heat or acidity?
Yes.
If a proteins shape is changed it has been?
denatured. This process can be caused by changes in temperature or pH levels, leading to disruption of the protein's structure and function.
What is the difference between denatured and coagulated proteins?
In denatured proteins, a loss of function is experienced. It is also part of the process of coagulation. Coagulation is a non-reversible process, which is the opposite of denaturing.
What is responsible for identifying and digesting damaged or denatured proteins?
Proteasomes are responsible for identifying and digesting damaged or denatured proteins. Proteasomes are large protein complexes that are found in eukaryotic cells.
What amino acids is structurally classified as being polar?
proteins
