Yeast Beta Glucan is a functional polysaccharide existing in the yeast cell wall, with β-1,3-D-glucan as the main chain and β-1,6-D-glucan as the branched chain. The molecular mass is about 240 Chemicalbook million, and about 10,000 glucose molecules are connected. Yeast glucan forms a tight network structure in the yeast cell wall, which plays an important role in maintaining the structural integrity of yeast cells and maintaining cell shape. Widely used in food, health products, cosmetics industry.
