Will Acids Denature Proteins?

Proteins are denatured by treatment with alkaline or acid, oxidizing or reducing agents, and certain organic solvents. Interesting among denaturing agents are those that affect the secondary and tertiary structure without affecting the primary structure.

Can proteins be denatured by heat or acid?

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).

What 3 things can denature proteins?

Temperature, pH, salinity, polarity of solvent - these are some of the factors that influence the shape of a protein. If any one or combination of these factors varies from normal conditions the shape (and function) of the protein will change. This change in shape is also called denatured.
