Comparison of different beta glucans from structure

Comparison of different beta glucans from structure

Glucan can be widely found in nature, including plants, fungi, bacteria, etc;

The differences of molecular structure lead to significant differences in their efficacy.

β-glucan structure-activity mechanism

The content of β-1, 3 - glucan is a key factor in its role. The length and number of branched chain is the key to the specific binding of the immune cells.

Bacterial Source: Single β-1, 3 - glucan cannot effectively bind to receptors on immune cells.

Grain Source: β-1, 4 - glucan cannot enhance the immune activity, and without β-1, 6

Branch,but cereal source beta glucan have been proved that it have good effective of Lowering LDL cholesterol and Promote cardiovascular health.

Mushroom Source: The degree of branching is high, the branch is short,and mushroom extract always have many other effective ingredients,then can Have very good comprehensive nutrition effect.

Yeast Source: Suitable length of branched chain and single β-1, 3- glucan backbone could

effect in the enhancing immune activity as best.

The difference between yeast glucan and oat glucan

1. The basic structure of Oat glucan is a linear polysaccharide which is connected by D-glucose with β 1-4, β 1-3 glycosidic bond. The rough ratio of these two glycosidic bond is about 7:3. and yeast glucan is connected by D-glucose, with β-1-3 glycosidic bond as the main chain, and β-1-6 glycosidic bond as a branched chain, as the content of β-1, 3 - glucan is the key factor of effect, so oat glucan immune reactivity is significantly lower than the yeast glucan.

2. Studies have shown that the yeast glucan and oat glucan can lower LDL, but the yeast glucan can significantly increase high-density lipoprotein (HDL), but oat glucan have no such function,so for regulate blood sugar level.lower cholesterol,adjustable insulin levels.the best choice will be oat beta glucan.

3. The research of Yeast glucan is broader and more in-depth, that it have some effects on the immune system, radiation damage and tumor recession. Scientists have found yeast beta-glucan-specific receptors on the cells which enhance immunity and anti-tumor immunity.
