Biological function of yeast cell wall polysaccharide

Biological function of yeast cell wall polysaccharide

1).Growth promoting effect

Yeast polysaccharide can significantly improve the body's ability to resist disease and stress, and increase lactobacillus in intestinal tract, while decrease the number of Escherichia coli. Promote vitamin synthesis and stimulate intestinal peristalsis, assist food digestion and nutrition absorption.

2).Antiviral effect

Not only has the direct inactivation effect, but also has the inhibition effect to the virus inside and outside the cell.

3).Enhance immune function

GluCan is one of the most important structural substances in yeast cell wall. GluCan is also found and confirmed to have the effect of improving immunity in the first study. Studies have shown that β -glucan is the matrix of immune reaction and has the following effects on immunity:

(l) Stimulate lymphocyte proliferation in animals;
(2) Activating macrophages in animals;
(3) Increase the ability of animals to produce natural killer cells;
(4) Induce non-specific immunity to candidiasis and improve survival rate.

Mannan is another important polysaccharide component of yeast cell wall. Because the mannan oligosaccharide structure and is very similar to receptors on the pathogenic bacteria in the intestines, and characterized with the class d has a strong combining ability, add cell wall polysaccharides for bacteria provides a rich source of mannose, avoiding the bacteria and the affinity between the colon wall, once the mannan oligosaccharides with these kind of butyl quality, can make the pathogen is no longer attached to the intestinal wall, However, the pathogenic bacteria could not use mannan-oligosaccharides as the energy source for their growth, so the pathogenic bacteria lacked energy because they could not use mannan-oligosaccharides. Because mannan-oligosaccharides are not degraded by digestive enzymes and thus carry pathogens through the intestine, they can prevent the colonization of pathogens. Therefore, it is also called "pathogen adsorbent" or "pathogen scavenger".

Regulation of intestinal microecological environment

Yeast polysaccharide has certain regulation effect on intestinal microecological environment

The main performance is:

(1) Yeast polysaccharide has the ability to adsorb pathogenic bacteria, it can reduce the number of intestinal pathogenic microorganisms such as Salmonella and Escherichia coli, promote the reproduction of beneficial active bacteria in the intestinal flora - lactobacillus, so that the imbalance of intestinal flora in a short period of time to correct, restore balance;

(2) Eliminate pathogenic microorganisms such as Escherichia coli and Salmonella through the immune effect on the body;

(3) based on the regulation of the body micro ecological balance, promote the intestinal ZhongGe gram-positive beneficial physiological active bacteria proliferation, inhibiting decay naturally gram negative bacteria, effectively reduce the endotoxin content in plasma, reduce serum endotoxin level, inhibit outside home by bacteria in the gut, prevent gut of gram-negative bacteria to the purpose of the transfer.
