Lysozyme is an enzyme that destroys bacterial cell walls by hydrolyzing the polysaccharide component of the cell wall. It is abundantly present in a number of secretions, including tears. This protein is present in cytoplasmic granules of the polymorphonuclear neutrophils and released through mucosal secretions such as tears and saliva. They can also be found in high concentrations in egg white. Lysozyme is expressed in myeloid cells, histiocytes, granulocytes, macrophages, and monocytes in human tonsil, colon and skin."}]}]}
