Lysozyme (also known as muramidase or N-acetylmuramide glycanohydrlase) is an alkaline enzyme that hydrolyzes mucopolysaccharides in pathogenic bacteria. Mainly by breaking the β-1,4 glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in the cell wall, the cell wall insoluble mucopolysaccharide is decomposed into soluble glycopeptide, which causes the cell wall rupture content to escape. Bacteria dissolve.
Lysozyme can also bind directly to negatively charged viral proteins, forming complex salts with DNA, RNA, and apoproteins, inactivating viruses. Therefore, the enzyme has antibacterial, anti-inflammatory, anti-viral and the like.
Lysozyme is abundant in secretions including tears, saliva, human milk, and mucus. It is also present in cytoplasmic granules of
the macrophages and the polymorphonuclear neutrophils (PMNs). Large amounts of lysozyme can be found in egg white. C-type lysozymes are closely related to alpha-lactalbumin in sequence and structure, making them part of the same family. In humans, the lysozyme enzyme is encoded by the LYZ gene.

Lysozyme is an alkaline enzyme that can hydrolyze mucopolysaccharides in bacteria.
Easily soluble in water, insoluble in acetone and ether. Lysozyme is easily destroyed by alkali, but in acidic environment, lysozyme is very stable to heat The optimal pH of lysozyme is 5.3~6.4, which can be used for low-acid food preservation; as a preservative, lysozyme has high safety, can be frozen or dried, and has stable vitality.
(1). Antibacterial effect:
Lysozymes can hydrolyze bacterial cell walls, leading to bacterial rupture and death. Especially for bacteria that develop resistance to conventional antibiotics, lysozyme can still effectively kill them.
(2). Anti-inflammatory effect:
Lysozyme can stimulate macrophages in the human body to secrete inflammatory factors such as interleukin, promote immune cell phagocytosis, and eliminate bacterial infections. It can also reduce inflammatory reactions, alleviate pain and discomfort.
(3). Stimulating the immune system:
Lysozymes can enhance the function of the human immune system, promote the activity and vitality of various immune cells in the body, and enhance the body's resistance and immunity.
(4). Improving respiratory diseases:
Due to the ability of lysozyme to hydrolyze bacterial cell walls, it has a certain therapeutic effect on respiratory diseases such as bronchitis and pneumonia. It can also alleviate symptoms such as nasal congestion, runny nose, and cough caused by upper respiratory tract infections.
(5). Promoting wound healing:
Lysozymes can stimulate cell growth and proliferation, accelerate wound healing, and aid in tissue repair after trauma.
(6).Regulating gut microbiota:
Lysozymes can help beneficial microbiota in the digestive tract rapidly reproduce, thereby improving the balance of gut microbiota, reducing the growth of harmful bacteria, and preventing intestinal infections.
(1). Food industry: Enzyme Lysozyme Powder can be used as a food preservative, added to dairy products, meat products, egg products, fruits and vegetables, etc. It can effectively inhibit the growth of bacteria and fungi, and extend the shelf life of food.
(2). Pharmaceutical field: Enzyme Lysozyme Powder can be used in pharmaceutical preparations, such as oral tablets, injections, eye drops, etc. It can help treat infectious diseases, such as respiratory tract infection, urinary tract infection, skin infection, etc. In addition, it can also be used to treat allergic diseases, tumors, etc.
(3). Biotechnology: Enzyme Lysozyme Powder can be used in biotechnology, such as DNA/RNA extraction, cell lysis, etc. It can help destroy cell walls, release intracellular molecules, and promote the progress of biological experiments.
(4). Cosmetics: Enzyme Lysozyme Powder can be used in cosmetics, such as face cream, lotion, facial cleanser, etc. It can help reduce the number of bacteria and fungi on the surface of the skin, prevent skin infections and inflammation, and promote skin metabolism and repair.
Omega 3 Fish Oil can effectively treat a variety of mental disorders, such as bipolar disorder, schizophrenia and dementia. For pregnant and lactating women, it is a safe and effective treatment.
Sucralose Powder is an artificially synthesized high-strength Sweetener commonly used as a low calorie sweetener in food and beverages. It has a very low content in the raw material, almost negligible calories, and has no significant impact on blood sugar and insulin levels. The sweetness of Sucralose is about 600 times that of sucrose, so only a very small amount of powder is needed to achieve the same sweetness effect. This makes it an ideal choice for many low calorie or sugar free foods.
L-fucose powder is an important six carbon monosaccharide with multiple biological functions. It plays a role in immune regulation, cell signaling, and anti-inflammatory processes. L-fucose is also considered beneficial for intestinal health and is used as a moisturizer and anti-inflammatory ingredient in certain cosmetics and skincare products. As a nutritional supplement, L-fucose may also be helpful for certain health conditions.
Mogroside 40% sweetness is 300 times that of sucrose, and its heat is zero. It has the effect of clearing away heat, moistening lung, relieving cough, moistening intestines and relaxing the bowels, and has a preventive and therapeutic effect on obesity, constipation, diabetes and so on.
D- mannose Powder, It can't be metabolized well in the human body. , but it can regulate the immune system, increase wound healing, inhibit tumor growth and metastasis, increase the survival rate of cancer, and avoid some bacterial infections.
