Polysaccharide-other

  • Fungal/Yeast Polysaccharides

The composition of the cell wall of yeast and filamentous fungi varies between species. However, there are structural similarities and the predominant sugars are limited to glucose, galactose, and mannose. These include chitin (β-1,4-N-actetylglucosamine) and β-1,3(β-1,6)-glucans, which are core elements that provide tensile strength to the cell wall; and surface mannoproteins (MP). Yeast mannan is a highly branched complex carbohydrate an α-1,6 backbone, with α-1,2; and α-1,3-linked mannose sidechains. Some sidechains are further branched through phosphate ester bonds. C. albicans mannan has a conserved core structure with S. cerevisiae but displays signature β-1,2 mannosyl residues at the termini of its sidechains.

  • Archaebacteria Polysaccharide

Mostly, the cell wall of Archaea is represented by a proteinaceous surface (S-) layer but there are a lot of other cell well variants. Archaea contain polysaccharides and proteins but lack peptidoglycan. For example, the cell wall of Halococcus morrhuae (H. morrhuae) is composed of a complex, highly sulfated heterosaccharide consisting of glucosamine, galactosamine, gulosaminuronic acid, glucose, galactose, mannose, glucuronic acid, galacturonic acid, N-acetylated amino sugars, and sulfated subunits. Different heteropolysaccharides (HP) are thought to be connected via glycine bridges.

  • Functions of Polysaccharide

The functional activity of polysaccharides mainly depends on molecular weight (MW), degree of branching, water-solubility, structure, configuration and so forth.

  • Polysaccharides serve as a taxonomic tool. For example, lichen polysaccharides have been used as a taxonomic tool and chemotaxonomic classification has resulted in clarification of conflicting taxonomic data.
  • The biological activities of fungal polysaccharides reported have been related to anti-tumor, anti-microbial, immune-stimulation or immunomodulatory activity, nutritional component, hypoglycemic activity and so on.
  • Polysaccharides have formed the basis of the development of serological tests for the diagnosis of systemic fungal infection since their presence in the biological fluids of infected immunocompromised patients is directly correlated to fungal growth.
