The most prominent and universal function of polysaccharide is to enhance the immune function of the body. It can improve the phagocytosis of macrophages and induce the production of interleukin, which has this immune promotion effect.
Improve the activity of B cells, increase the secretion of various antibodies, strengthen the body's humoral immunity, and activate the complement system through different ways. Some polysaccharides activate complement through alternative pathways.
2. Anti-tumor function
Tumor is a serious threat to human health. Since the discovery of anti-tumor effect of yeast polysaccharide in 1950s, many anti-tumor polysaccharides have been isolated. As far as the anti-tumor effect of polysaccharide is concerned, the polysaccharide that induces macrophages to produce tumor necrosis factor has anti-tumor activity.
Extended data:
The active polysaccharide also has anti-mutation, hypolipidemic and antiviral effects.
Mutation is the premise of tumorigenesis. The so-called mutation refers to the process that normal cell genes that regulate cell growth, proliferation and generation in human body are mutated, activated and overexpressed under the action of some genetic factors or non-genetic factors, which leads to normal cell canceration.
At present, it has been found that polysaccharides with antimutagenic activity include ginseng polysaccharide and so on. Hyperlipidemia refers to the abnormal increase of one or more substances in the blood, which can directly lead to heart diseases such as atherosclerosis and coronary atherosclerosis.
Therefore, it is of great significance to actively prevent and treat hyperlipidemia. Polysaccharides with hypolipidemic activity have been found, such as kelp polysaccharide, brown algae polysaccharide, sugarcane polysaccharide, chondroitin sulfate, ganoderma lucidum polysaccharide, tea polysaccharide, laver polysaccharide, konjac polysaccharide and so on.
