Oligosaccharides

Oligosaccharides are saccharide polymers composed of three to ten units of monosaccharides, connected via glycosidic linkages, similar to disaccharides. They are usually linked to lipids or amino acids glycosic linkage with oxygen or nitrogen to form glygolipids and glycoproteins, though some, like the raffinose series and the fructooligosaccharides, do not. They have roles in cell recognition and cell adhesion.
