|
|
The order of amino acids is changed when the protein overheats.
|
|
|
The bonds between amino acids are broken by condensation.
|
|
|
Parts of the protein become linked together by hydrolysis.
|
|
|
The three-dimensional structure of the protein is altered.
|
Detailed explanation-1: -The denaturation of the protein causes the weak hydrogen bonds which are involved in protein interactions to produce three dimensional structures. When a protein is denatured, the different structures such as secondary and tertiary protein are broken.
Detailed explanation-2: -Denaturation and protein folding If the temperature or pH of a protein’s environment is changed, or if it is exposed to chemicals, these interactions may be disrupted, causing the protein to lose its three-dimensional structure and turn back into an unstructured string of amino acids.
Detailed explanation-3: -As a result of denaturation, globules get unfolded and helixes get uncoiled. Secondary and tertiary structures of protein are destroyed, but the primary structures remain unaltered. It can be said that during denaturation, secondary and tertiary-structured proteins get converted into primary-structured proteins.
Detailed explanation-4: -Denaturation of the proteins is a condition when the unique three-dimensional structure of a protein is exposed to changes. Due to changes in temperature, pH or other chemical activities, the hydrogen bonds present in the proteins get disturbed.
