Molecular Structure And Chemical Function Of Yeast Polysaccharides

Molecular structure:
In terms of molecular weight, there are polysaccharides ranging from 5000 molecules to over 106 molecules. Polysaccharides are those composed of at least 10 monosaccharides in a sugar chain bound by glycosidic bonds. Short chains with less than 10 are called oligosaccharides. However, in terms of sugar chains, even oligosaccharides, which bind proteins and lipids to oligosaccharides, belong to polysaccharides in a broad sense if they belong to high molecular weight. Therefore, they are specifically referred to as conjugated polysaccharides or glycoconjugates (glycoproteins, glycolipids, proteoglycans).
Chemical function:
Yeast polysaccharides have the function of storing bioenergy (such as starch, glycogen, inulin) and supporting structures (such as cellulose, chitin, and mucopolysaccharides). However, the polysaccharide components of the cell membrane and cell wall are not only supportive substances, but also directly participate in the process of cell division, and in many cases become active sites for mutual recognition structures such as cells and cells, cells and viruses, cells and antibodies.
Polysaccharides have no sweetness and cannot form a true solution in water. They can only form colloids and have no reducing or rotational properties, but they have optical activity.
