EXPERIMENT 2

Heat Effect on Proteins

supplies kinetic energy to protein molecules, causing their atoms to vibrate more rapidly and disrupting weak hydrogen bonding and dispersion forces.

Alcohol Effect on Proteins

engages in intermolecular hydrogen bonding with protein molecules, disrupting intramolecular hydrogen bonding within the protein.

Strong Acid Effect on Proteins

disrupt protein salt bridges by altering the pH, leading to the dissociation of cations and anions in solution.

Strong Base Effect on Proteins

disrupt protein salt bridges by altering the pH, leading to the dissociation of cations and anions in solution.

Heavy Metals Effect on Proteins

form strong bonds with carboxylate anions or SH groups of amino acids, disrupting ionic bonds and disulfide linkages.

Alkaloidal Reagents Effect on Proteins

combines with positively charged amino groups in proteins to disrupt ionic bonds.

Picric Acid

Surface Anesthetic Ointment

Tannic Acid

Topical Skin Treatment

Silver Nitrate (AgNO3)

Anti-infective agent for wound and/or burn treatments

Copper Sulfate (CuSO4)

Pesticide

Concentrated Sodium Hydroxide

also known as caustic soda, is used in cleaning and degreasing applications due to its ability to break down and denature proteins. It is commonly found in household drain cleaners and industrial cleaning products.

Concentrated Nitric Acid (HNO3)

used for sample digestion. It helps break down organic materials, including proteins, into simpler forms, allowing for the analysis of elemental composition or specific compounds in the sample.
