Nature of Proteins  
Effect of pH on solubility, denaturing proteins, hydrolysis in strong base, binding to coomassie blue, dying wool and cotton, gel filtration column, reaction of ninhydrin with amino acids and precipitating protein with ammonium sulfate are demonstrated.
Proteins / Peptides
Protein Reactions  
Curdling milk, decomposition of hydrogen peroxide by catalase, glucose oxidase activity, hydrolyzing of sucrose with invertase, and using an enzyme to halt the Briggs-Rauscher reaction are demonstrated. Inhibiting the enzyme HIV-1 protease may slow the spread of AIDS.

Denaturation of Protein by Strong Acid  John W. Moore, Jerrold J. Jacobsen, Gary Trammell, Kristin Johnson
"Strong acid denatures egg white proteins.This video contains voiceover:""The tertiary structure of egg white proteins is held together by hydrogen bonding and hydrophobic interactions. Adding strong acid to the protein disrupts the intermolecular forces, and the tertiary structure is lost. The loss in protein structure is called denaturation. The proteins precipitate, forming a white solid."""

Halting the Briggs-Rauscher Oscillating Reaction  
The Briggs-Rauscher reaction is demonstrated in three different ways. Catalase from a liver extract decomposes the hydrogen peroxide in an Briggs-Rauscher reaction, stopping the oscillations.
