Question

• A. Lipase
• B. Protease
• C. Cellulase
• D. Amylase

Answer 1

Answer: (A)

Lipases:

1. Lipases are enzymes that digest lipids.
2. They attack stains containing fats and oils by cutting lipid molecules into smaller pieces.
3. These smaller pieces mix more easily with surfactants, boosting the effect of surfactants in detergent and removing greasy stains far more effectively.
4. Lipases are used in detergent industries to minimise the use of phosphate-based chemicals in detergent formulations.
5. The use of lipase in household laundry reduces environmental pollution and enhances the ability of detergent to remove tough oil or grease stains.
