M 8: Protein Denaturation (Part 2)

Alkaloidal reagents disrupts Electrostatic Attraction and Hydrogen bonds

Tannic acid has been extensively used in the treatment of burns. When this substance is applied to a burn area, it causes the protein to precipitate as a tough covering, thus reducing the amount of water loss from the area. It also reduces exposure to air. Newer drugs have taken the place of tannic acid for burns, but an old-fashioned remedy still in use for emergencies involves the use of wet tea bags.

TCA (Trichloroacetic Acid) peel is a non invasive treatment used to treat skin discolorations, scarring, and wrinkles. These peels are used to clear away dead skin cells to reveal the newer and smoother skin layers below.

Strong Acids and Bases disrupt Electrostatic Attraction and Hydrogen bonds

Formation of the yellow stain as concentrated nitric acid comes into contact with skin.

Strong Acids and Bases disrupt Electrostatic Attraction and Hydrogen bonds

Adding acids in making cheese

Strong Acids and Bases disrupt Electrostatic Attraction and Hydrogen bonds

The need to wear goggles in a chemistry laboratory to avoid serious eye damage such as clouded cornea.

Organic Solvents (Ethanol, 2-Propanol, Acetone, Phenol) disrupt Hydrogen bonds

Use of isopropyl and ethyl as antiseptic and as a disinfectant

Organic Solvents (Ethanol, 2-Propanol, Acetone, Phenol) disrupt Hydrogen bonds

Use of Phenol to denature the protein in the nail bed that causes ingrown nails

Organic Solvents (Ethanol, 2-Propanol, Acetone, Phenol) disrupt Hydrogen bonds

Alcohols are an important type of denaturing agent. Denaturation of bacterial protein takes place when isopropyl and ethyl alcohol is used as a disinfectant, hence the common practice of swabbing the skin with alcohol before giving an injection.

Reducing agents disrupt Disulfide bonds

The use of povidone-iodine as an antiseptic in cleaning wounds and betadine surgical scrub

Detergent

___________ affects R-group interactions

Thiol Group

Reducing agents ass hydrogen atoms to make the __________

Split it apart

If oxidizing agents cause the formation of a disulfide bond, then reducing agents of course act on any disulfide bonds to __________

Microwave Radiation disrupt Hydrogen bonds

This causes violent vibrations of molecules that disrupt hydrogen bonds

Ultraviolet Radiation

Radiation therapy for cancer treatment

Ultraviolet Radiation

The effect of __________ from the sun, ionizing radiation is similar to that of heat. Denatured skin proteins cause sunburn.

Violent Whipping or Shaking

Cause molecules in globular shapes to extend to longer lengths, which then entangle like beating egg white into a meringue.
