HUMAN NUTRITION

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. Polysaccharides are an important class of biological polymers.

Detailed explanation-2: -The polysaccharides are the most abundant carbohydrates in nature and serve a variety of functions, such as energy storage or as components of plant cell walls. Polysaccharides are very large polymers composed of tens to thousands of monosaccharides joined together by glycosidic linkages.

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.
