Polysaccharide (English: Polysaccharide) is composed of multiple monosaccharide molecules dehydrated and polymerized, connected by glycosidic bonds. It can form a straight chain or a long branched chain. After hydrolysis, the corresponding monosaccharides and oligosaccharides are obtained. . For example, starch and glycogen are used to store energy, and cellulose and chitin are used to form biological structures.

Polysaccharides are often composed of lightly modified repeating units. Due to their different structures, polysaccharide polymers and the monosaccharide molecules that make up them have very different properties and may be amorphous or even insoluble in water.

Extended information

Scientists have warned: "Without immunity, life will cease." Research by domestic and foreign experts has proven that all large fungi, almost without exception, have Very good immunomodulatory effect, mainly due to the "polysaccharides" they contain.

Polysaccharides are very common in daily life. The starch in the rice and noodles we eat, and the cellulose in vegetables are all a type of polysaccharides. There are also some health-preserving ingredients in life, such as shiitake mushrooms, poria cocos, and tremella fuciformis. These also contain polysaccharides, which are called lentinan, poria cocos polysaccharide, and tremella fungus polysaccharide respectively.

These polysaccharides have been proven through cell experiments or animal experiments to have certain specific activities or effects, such as enhancing immunity, relieving physical fatigue, delaying aging, etc. The polysaccharides added to some health foods are polysaccharides with specific activities or effects.
