What and where are lysozymes found?

Lysozymes are enzymes that catalyse the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetylglucosamine residues in bacterial cell walls. They are found in a variety of sources, including:

- Tears, saliva, and other bodily fluids: Lysozymes are present in the tears, saliva, and other bodily fluids of humans and other animals. They help to protect the body from bacterial infections by breaking down the cell walls of bacteria that enter the body.

- Egg white: Lysozyme is also found in egg white. It is responsible for the antibacterial properties of egg white and helps to protect the egg from spoilage.

- Milk: Lysozyme is present in milk and other dairy products. It helps to inhibit the growth of bacteria in milk and milk products.

- Lysosomes: Lysozymes are also found in lysosomes, which are organelles that are responsible for digesting and recycling cellular material. Lysozymes help to break down the cell walls of bacteria that are engulfed by lysosomes.
