Detailed explanation-1: -As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three to ten monosaccharide units, but the precise cutoff varies somewhat according to the convention.
Detailed explanation-2: -Disaccharides contain two sugar units. Oligosaccharides contain 3 to 10 sugar units. Polysaccharides contain more than 10 sugar units.
Detailed explanation-3: -Oligosaccharide is the short chain of monosaccharide unit which composed of 3-10 molecules connected by glycosidic linkage. The most common example of oligosaccharide is raffinose. It is a trisaccharide found in many plants and composed of galactose, glucose and fructose.
Detailed explanation-4: -A polysaccharide is a large molecule made of many smaller monosaccharides. Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers, or polysaccharides. A polysaccharide is also called a glycan.
