Oligosaccharides and polysaccharides

Oligosaccharides and polysaccharides up the chain monosaccharide units bound glycosides? Between the two countries, the difference is based on the monosaccharide units are involved in the chain. Oligosaccharide usually consists of three score and ten monosaccharides, polysaccharides and has more than ten monosaccharide units. Meaning, as high carbohydrate must fall into each category depending on personal opinions. Examples of oligosaccharides include the disaccharides mentioned above, the trisaccharide raffinose and the tetrasaccharide stachyose.

Oligosaccharides found as a common form of protein posttranslational transformation. Posttranslational modifications include the Lewis and ABO oligosaccharides responsible for blood group classifications and other tissue incompatibilities, the alpha-Gal epitope responsible for hyperacute rejection in xenotransplantation GlcNAc and O-modification.

Polysaccharides is an important lesson in bio-polymers. Their role in living organisms as a rule, or structure or storage related. Starch (glucose polymer) used as a storage polysaccharide in plants, found in the form of both amylose and branched amylopectin. In animals, the glucose polymer structure is more densely branched glycogen, sometimes called the "juice of life. Properties Glycogen is metabolized quickly, which benefits the lives of active mobile animals.

Cellulose and chitin polysaccharides structural example. Cellulose is used in cell walls of plants and other organisms, and should be abundant organic molecule on earth. [9]: It has many uses, including a significant role in the textile and paper industries and is used in the production of rayon (viscose during the process), cellulose acetate, celluloid, and nitrocellulose material. Chitin is a similar structure, but contains nitrogen party branches, increase the military strength. It is located in the exoskeletons of arthropods and cell walls of some fungi. It also has many uses, including surgical threads.
