The chemical in tears that protects the body against bacteria is lysozyme. This enzyme has antibacterial properties, as it breaks down the cell walls of certain bacteria, leading to their destruction. Lysozyme is part of the body's innate immune response and helps maintain the health of the eyes and surrounding tissues by preventing infections.

What chemical in your tears kills?
Your tears contain the enzyme lysozyme. This chemical disrupts the cell walls of gram-positive bacteria by digesting the peptidoglycan in them. This enzyme is also found in your saliva and is an example of a non-specific immune response.
Is tears a chemical barrier against pathogens?
yes, tears prevent pathogens from entering the eye. when an irritation occurs the eye produces a salty liquid (tears) to clean the eye from any dust or pathogens. eyelashes also prevent pathogens and dust from entering. In terms of a chemical barrier, your tears contain the enzyme lysozyme which can disrupt the cell walls of gram-positive bacteria by digesting the peptidoglycan in them. This enzyme is also found in your saliva.
How do tears fight against pathogens?
True A+
Does tears contain lysozyme?
Yes, tears do contain lysozyme, an enzyme that helps protect against bacterial infections by breaking down the cell walls of certain bacteria.
Can tears destroy bacteria?
Tears contain an antibacterial substance :)
Is lysozyme in saliva and tears to destroy bacteria a body defense?
Yes, lysozyme is found in saliva and tears and acts as a defense mechanism by breaking down the cell walls of bacteria, thereby helping to protect the body against infection.
Tears contain antibacterial substances that destroy many bacteria?
Basic a level knowledge: Tears are a form of chemical barrier from infection. The enzyme lysozyme is found in tears which kills of some bacteria which helps prevent pathogens entering the body and causing infection. I hope this helps, I'm unsure how the enzyme kills the bacteria as I was only aware that enzymes are catalysts that lower the activation energy in a reaction. If any one knows I'll be very grateful. :) Xxx
How do tears act as barriers against harmful organisms?
Human tears contain the enzyme lysozyme which disrupts the cell walls of gram-positive bacteria by digesting the peptidoglycan in it. This enzyme can also be found in your saliva.
The chemical found in tears and saliva that hydrolyzes the peptidoglycan in certain bacterial cell walls is what?
The chemical found in tears and saliva that hydrolyzes the peptidoglycan in certain bacterial cell walls is lysozyme. Lysozyme functions as an antimicrobial by breaking down the cell walls of bacteria, leading to their destruction.
Is the tear duct a physical barrier or a chemical barrier?
it is a chemical barrier because it produces tears that are chemicals. also- for your information, skin is a physical barrier along with the nose and mucus and cilia. sebum and stomach acid are chemical. :D
What are the protective enzymes in sweat and tears called?
The protective enzymes in sweat and tears are called lysozymes. These enzymes help to break down the cell walls of certain bacteria, providing a protective barrier against infections.
How does tears compare to blood pH?
tears are 5.0 blood is 7.4 but the both can kill bacteria. with the acid in them.
