Mannose is a monosaccharide and a six-carbon sugar. It is a constituent of a variety of polysaccharides. It exists in the free state in some plant peels, such as citrus peels, peaches, apples and other fruits with a small amount of free mannose, ivory palm seeds, yeast, red algae, serum globulin, ovomucoid, and tuberculosis D-mannose-containing glycans.
Mannose, currently the only clinically useful glycogen nutrient, is widely distributed in body fluids and tissues, especially in nerves, skin, testes, retina, liver and intestines. It is directly used to synthesize glycoproteins and is involved in immune regulation. Many diseases are caused by the lack of enzymes in mannose saccharification. Its physiological effects in the human body are:
1) Regulate the immune system
2) There are four types of receptors on the surface of macrophages to capture antigens, all of which have mannose
3) Increase wound healing
4) Anti-inflammatory effect
5) Inhibit tumour growth and metastasis and increase the cancer survival rate
6) Can avoid certain bacterial infections, such as urinary tract infections
Scientists have found that there may be a relationship between community-acquired pneumonia and mannose-binding lectin, and this may become a breakthrough in the treatment of pneumonia; mannose effectively relieves the condition of mice with type 1 diabetes virus, and may be useful for the treatment of type 1 diabetes in humans It is of great significance; the application of mannose in Drosophila melanogaster has significantly prolonged the life span of drosophila, and mannose may have the effect of extending human lifespan; the British Cancer Research Council announced that in the laboratory, mannose effectively inhibited the development of cancer Reproduction is another big hope for humans in fighting cancer.
