Why are primary structures not affected by denaturation? 
Ans: Primary structures have strong peptide bonds so they must be destroyed by 
hydrolysis. 
How does changes in pH result in denaturation of proteins? 
Ans: It alters the charges on the side chains of proteins 
How does heat result in denat...
