Definition:

This is a basic polypeptide. It has antibacterial action; it is bacteriostatic (prevents bacteria from growing) in the gastrointestinal tract, especially against gram-positive bacteria. It is instrumental to the immunological system as there is 3,000 times more lysozyme in breast milk than any other form of milk -- the levels are the same in both term (baby is born after 37 weeks) and preterm milk (baby is born prior to 37 weeks). Lysozyme also contains anti-inflammatory properties.
