Protists are the members of an informal grouping of diverse eukaryotic organisms that are not animals, plants or fungi. They do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates.

Oligosaccharide is a carbohydrate polymers comprise three to ten monosaccharides, or, simple sugars.
They were linked together mostly by O-glycosidic bond through condensation reaction between an anomeric carbon of a monosaccharide and the other.
