Oligosaccharides are saccharide polymers containing only about three to six simple sugars as components.
A and B blood types are marked by two different oligosaccharide glycolipids that are embedded in the cellular membranes of red blood cells.
Though these oligosaccharides are similar enough to have the same functions, they are dissimilar enough that in a foreign system they will be attacked by the body’s immune system, which is why blood must be typed prior to transfusing.

 Phosphorylase recognition and phosphorolysis of its oligosaccharide substrate: answers to a long outstanding question
Numerous attempts to observe binding of oligosaccharide substrates with rabbit muscle glycogen phosphorylase (GP) in the active R state were not successful, probably because of the low affinity of the enzyme for linear oligosaccharides.
Co-crystallization of MalP with acarbose led to oligosaccharide binding in sub-sites +1 to +4 and the identification of the further sub-sites +3 and +4 (O'Reilly et al., 1999).
Once the position of the oligosaccharide had been partially refined, the substrate phosphate anion in the ternary complex was located first by positioning the phosphorous atom from the location of the highest peak in a second difference Fourier calculation, followed by positional and B factor refinement.

 YSK Functional Material World - Chitosan oligosaccharide   (Site not responding. Last check: 2007-10-24)
Chitosan oligosaccharide, obtained through the decomposition of chitosan, is a deacetylated chitin oligosaccharide, and is a type of oligosaccharide that consists of a chain of multiple D-glucosamine molecules.
Among its currently known characteristics and features, it (1) is a saccharide that is not decomposed by enzymes within the digestive organs and is difficult to digest;(2) has antibacterial properties; and (3) improves liver function.
Unlike the polysaccharides chitin and chitosan, which are not water-soluble and therefore have only limited use as additives in food products, chitosan oligosaccharide, like chitin oligosaccharide, is water-soluble, making it suitable for use as an ingredient in food products.
