Question 2

If lysozyme is found in sweat,saliva,and tears,why can't it be used as an antibiotic against serious disease agents?

Accepted Answer

Lysozyme is an enzyme that is found in sweat, saliva, and tears, and it does have some antibacterial properties. It works by breaking down the cell walls of certain bacteria, making it more difficult for them to survive. However, lysozyme is not effective against all types of bacteria, and it is not strong enough to combat serious disease agents such as those that cause tuberculosis, pneumonia, or other severe infections. Additionally, using lysozyme as an antibiotic would not be practical because it would require extremely high concentrations to be effective, and it would likely have negative effects on the body's natural microbiome. Therefore, while lysozyme does have some antibacterial properties, it is not a suitable antibiotic for serious disease agents.
