Lactoperoxidase is an enzyme found in various bodily fluids, including saliva, milk, and tears. It plays a crucial role in the immune system by producing antimicrobial compounds that help protect against bacteria and other pathogens. This enzyme is particularly important in maintaining oral health and preventing infections. In addition to its natural presence in the body, lactoperoxidase is also used in food preservation and as an additive in some dental products. Its ability to inhibit the growth of harmful microorganisms makes it valuable in enhancing food safety and promoting oral hygiene.
