petide bonds
A protein is denatured because of high temperatures or changes in pH. When it is denatured, it means that the protein has lost its original shape and therefore, it cannot function properly anymore.
When a protein is denatured, its turnover number may decrease because denaturation can disrupt the protein's active site, leading to a decrease in its catalytic activity. The turnover number is a measure of how efficiently an enzyme can catalyze a reaction, so if denaturation affects the enzyme's ability to function properly, the turnover number may be altered.
When a protein has lost its 3D structure it becomes polypeptide chain with some secondary structure elements are they may simply degraded to it primary structure which is polypeptide chain.3D structure is a native structure of protein molecule where it can have the correct folding stabilized by its intra and inter molecular interactions among its residues.Proteins can loose its structure when they are exposed to a denaturing condition which is change in buffer environment such as pH, temperature,ion salts, metals and detergents such as SDS can unravel the proteins structure. Reducing agents such as DTT or 2-mercaptoethanol or often used with heat (95 degrees) to denature the protein completely while resolving them on the gel.
Enzyme become denatured.
Extreme heat, high or low pH, ionization of liquid medium, and a change in environment. The last one needs a little more explanation. If a protein is meant for a liquid-liquid environment, and it is brought into an air-liquid environment, it may denature. Proteins form because of the folds created from hydrophilic and hydrophobic folding. If there is no water in which these bonds form, the protein will denature.

The high heat or radiation can cause the protein molecule to denature, losing its original structure and function. This can lead to the protein becoming non-functional and potentially harmful to the cell or organism.
If a protein's hydrogen bonds are broken, its structure may be disrupted, leading to a loss of function. Hydrogen bonds are important for maintaining the specific shape and stability of proteins, and any disruption in these bonds can alter the protein's ability to bind to other molecules or carry out its biological function.
An enzyme that has lost its ability to function properly is often referred to as a denatured enzyme. This can occur due to changes in temperature, pH, or the presence of certain chemicals that disrupt the enzyme's structure. Once denatured, an enzyme may no longer be able to catalyze reactions effectively.
First of all, a protein consists of chains of amino acids and a single amino acid is coded by one codon of DNA. Mutations are able to insert, delete, replace and shift codons, which can result in amino acids being changed, removed or added, which would affect the protein that the amino acids are building.For example;Here is a strand of DNA in which the three codons in the middle codes for the amino acids.....TGG ATT ATG GAG TTC....-----> Isoleucine, Methionine, Glutamic acidSay that the strand of DNA has it's reading frame mutated (shifted).....GGA TTA TGG AGT TC....-----> Leucine, Tryptophan, SerineNotice how completely different amino acids arose from the mutation. Such a change may effect the protein's characteristics, as well as the phenotype of the organism.

Denatured proteins typically lose their natural structure and, consequently, their biological function. The denaturation process disrupts the protein's specific shape, which is essential for its activity, such as enzyme catalysis or receptor binding. While some denatured proteins may regain functionality upon refolding, most cannot do so and remain inactive.
When a protein is denatured, its molecular shape is altered. This alteration may or may not be reversible.What remains is the primary structure of the chain(s) of the protein, in other words the sequence of the amino acids.The tertiary structure referers to the overall three dimensional shape will be lost
There are several things that can cause proteins to denature.Change in temperatureAlterations in pHHigh concentrations of polar substancesNonpolar substances (when hydrophobic groups are needed to maintain the structure)All these things represent a drastic change to the protein structure, and the protein can become denatured.
True. When a protein is denatured, its three-dimensional structure is altered, disrupting the interactions that maintain its specific shape. This change often leads to the loss of its biological function, as the active site or binding sites may be rendered ineffective. Denaturation can result from factors such as heat, pH changes, or chemical agents.
