"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)." wat does it meannn

"Denaturation destroys the primary structure of the protein, and the protein breaks down to monomers. Different amino acids are substituted into the sequence, so the protein's properties change. The protein's pH changes, and the change causes the protein to lose its functionality." hmmm
