Detailed explanation-1: -Denaturation is described as the change in the structure and function of a protein.

Detailed explanation-2: -Proteins change their shape when exposed to different pH or temperatures. The body strictly regulates pH and temperature to prevent proteins such as enzymes from denaturing. Some proteins can refold after denaturation while others cannot.

Detailed explanation-3: -Protein takes a specific three-dimensional structure to maintain biological functions in aqueous solution. When the protein is heated, thermal motion and other factors break down the protein structure. This is known as thermal denaturation.

Detailed explanation-4: -A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).
