Clinical Importance of Both Homoglycans and Heteroglycans

Polysaccharides are plentiful natural polymers found in plants, animals and microorganisms with exceptional properties and important roles to sustain life.

  • They are rich in nutritional value and the positive effects on our immune and digestive functions and detoxification system.
  • Polysaccharides are used as demulcents, in drug formulations, for dental-impression materials, dusting powders, hemostatics, and for the treatment of mild intestinal disorders.
  • They can also be used to distinguish normal from malignant cells, in cell surface investigations, radioimmunoassay, and in targeting drugs to specific tissues.

Polysaccharides

Polysaccharides are complex carbohydrates made up of multiple sugar (monosaccharide) units linked together. They are essential macromolecules in biology and serve various functions in living organisms. Polysaccharides play a crucial role in energy storage, structural support, and cellular recognition. Let us have a glance over the topic of polysaccharides.

What is Polysaccharides?

A polysaccharide is a type of carbohydrate, specifically a complex carbohydrate, that consists of multiple monosaccharide (simple sugar) units linked together. These long chains of sugar molecules can be quite large and complex. Polysaccharides serve various important functions in living organisms, such as energy storage, structural support, and cellular recognition....

Structure of Polysaccharides

The process of formation of polysaccharides is the same as that of monosaccharides via glycosidic bonds. These glycosidic bonds comprise an oxygen molecule bridging two carbon rings. The bond is formed when a hydroxyl group is lost from the carbon of one molecule, while the hydrogen is lost by the hydroxyl group of another monosaccharide. Because two molecules of hydrogen and one of oxygen are ejected, the reaction is a dehydration reaction.  The structure of the molecules being combined resolutes the structure and properties of the resulting polysaccharides....

Heteropolysaccharides in Archaebacteria

Like Eubacteria, Archaea contain a cell wall made up of various polysaccharides and glycoconjugates. There is the absence of peptidoglycan in archaea, but they still form rigid cell boundaries that confer resistance to high internal osmotic pressure. They have D-type of amino acids instead of L-amino acids. In some archaeal species, the S-layer can be further supported by polysaccharides, by a second S-layer sheet, or by additional surface glycoproteins....
