It is the net effect of alterations in the biological, chemical, and physical properties of the protein by mild disruption of its structure.
Protein Denaturation
Enzyme Action
Coconut Milk
Chemistry
These are some of the factors that influence the shape of a protein EXCEPT ONE:
Temperature
pH
salinity
glucose
It involves the breaking of many of the weak linkages, or bonds within a protein molecule that are responsible for the highly ordered structure of the protein in its natural state.
Proteins
