Lysozyme (lysozyme), also known as muramidase (muramidase) or N-acetyl cell wall mass polysaccharide hydrolase (N-acetylmuramide glycanohydrlase), a hydrolysis pathogens mucopolysaccharide alkaline enzyme. Primarily through the destruction of the cell wall of N-acetyl muramic acid and N-acetyl glucosamine, β-1, 4 glycosidic bonds, so that the cell wall insoluble mucopolysaccharide broken down into soluble glycopeptide, lead to cell walls to rupture the contents to escape leaving Bacterial dissolved. Lysozyme can be used with the negatively charged viral proteins directly bind to DNA, RNA, apoprotein formation of double salts, so that the virus inactivation. Therefore, the enzyme has antibacterial, anti-inflammatory, anti-virus role. 
 Lysozyme application of a medical application 
 Material can be used as a bactericidal effect of natural resistance to infection. Is antibacterial, antiviral, bleeding, swelling, pain and accelerate tissue recovery functions. Clinic for chronic rhinitis, acute and chronic pharyngitis, oral ulcers, chicken pox, herpes zoster and verruca plana. Can also be combined with the antimicrobial agents to treat various bacterial and viral infections. Oral and intramuscular. Orally, 3 to 5 / (enteric-coated tablets containing 10mg), 3 times / day. Mouth with 1 / (buccal tablets containing 20mg), 4 to 6 times / day. Topical: 1% to 2% solution drip, rubbed or direct dusting. Intramuscular injection, 50mg to 100mg / 1 or 2 times / day. Drops: 2% solution. The side effects sometimes less severe allergic reactions. Chloride, lysozyme wider medical effects, with sputum dispersed, the suppression of bleeding, tissue repair, anti-inflammatory analgesic, anti-viral role, thus lysozyme chloride pharmaceutical anti-inflammatory Xiaozhi, colds, skin diseases and eye, nose and throat medicine. 
 Two food preservation applications: 
 Can be used as a preservative, its main function is the hydrolysis of bacterial cell wall, inside the cell, after phagocytosis of pathogens from the damaging effects. Enzyme in Gram-positive bacteria Bacillus subtilis, the radiation-resistant Micrococcus decomposition. The bacteria Escherichia coli, Proteus and Vibrio parahaemolyticus and other Gram-negative bacteria also have a certain degree of dissolution, its most effective concentration of 0.05%. Used in conjunction with phytic acid, polyphosphate, glycine can increase the preservative effect.
