Question

why rubbing alcohol on skin is an example of denaturation?​

Answer 1

Answer:

Denatured Alcohol

The term ‘denatured alcohol’ refers to alcohol products adulterated with toxic and/or bad tasting additives (e.g., methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone), making it unsuitable for human consumption. The most common additive used is methanol (5–10%), giving rise to the term ‘methylated spirits.’ Denatured alcohol is used as a lower-cost solvent or fuel for home-scale or industrial use, compared with the heavily taxed pure alcohol and alcohol used in beverages.

Answer 2

Explanation:

• On the skin, a 70% alcohol solution is utilized as a disinfectant. Alcohol at this concentration can enter the bacterial cell wall and denature the proteins and enzymes inside the cell. Alcohol denatures proteins by breaking intramolecular hydrogen bonding between side chains.

• It's a type of denatured alcohol made from a specific solution that contains around 70% pure ethanol or isopropyl alcohol in concentrated form.
