Lysozyme defends us from the any bacterial infection. It is a small enzyme that attacks the cell walls made of carbohydrate chains of bacteria. Bacteria build a tough skin of carbohydrate chains, linked by short peptide chains , that protect bacterial membrane against the cells high osmotic pressure. Lysozyme catalyse these carbohydrate chains, destroying the structural integrity of the cell wall. The bacteria destroy them self under their own internal osmotic pressure. This catalytic activity is non-specifically targeted to the bacterial cell membranes and related with general non-specific organism protection .
Lysozyme, also known as Globulin G1 or Mucopeptide N-acetylmuramoylhydrolase was discovered by Alexander Fleming during his search for medical antibiotics.
Long time, he use everything to bacterial culturesto slow their grows . He find lysozyme by chance. One day , when he had a cold, he added a drop of mucus to the bacterial culture and , much to his surprise, it killed the bacteria. He had discovered one of our own natural antibacterial protection. It can be applied on surfaces , but cannot rid the entire body of disease, because it is too large to travel between cells.
Lysozyme protects all open areas subjected to high bacterial grows . In our website you can find detailedlysozyme pictured from egg whites, where it protect the proteins that will nourish the developing chick. It is the first protein ever to have its structure solved . Our tears and mucus contain lysozyme to resist infection of our exposed surfaces. Our blood is the worst place to have bacteria grow, as they would be delivered to all corners of the body. In the blood, lysozyme provides some protection, together along with the more powerful methods employed by the immune system.
Researches reveals that lysozyme from egg white or human urinary lysozyme is able to stop HIV entering into human body , which mean that lysozyme have some reasonable anti-HIV activity. Unfortunately there is no way to use lysozyme against HIV infection which already infect human body. The presence of lysozyme significantly reduce chances to have infection during contacts with infected substances.
