Detailed explanation-1: -Coagulation happens when the protein molecules unfold during denaturation, bump into other protein molecules, and combine together in clumps to become a solid. Heat will denature egg white protein; there are several other methods one can use to denature egg white protein.

Detailed explanation-2: -The coagulation of protein is called denaturing. Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures.

Detailed explanation-3: -Denaturation: the chemical bonds have broken and the protein molecule has unfolded and changed. shape. Coagulation: the joining together of lots of denatured protein molecules, which changes the appear-ance and texture of the food.

Detailed explanation-4: -What is denaturing and how does it happen? 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).
