Four polysaccharides are starch, glycogen, cellulose and chitin. The function of starch and glycogen are to store energy with cells within a body. Cellulose and chitin are designed to protect cells. Polysaccharides are comprised of multiple monosaccharides. A typical polysaccharide chain is formed of hundreds of individual monosaccharides.
Nutrition polysaccharides are common sources of energy. Many organisms can easily break down starches into glucose; however, most organisms cannot metabolize cellulose or other polysaccharides like chitin and arabinoxylans. These carbohydrate types can be metabolized by some bacteria and protists.

Polysaccharides Types, Digestion, Function and Benefits. Digestible polysaccharides, such as starch, are digested (broken down) in the mouth and small intestine in several steps that eventually yield glucose, which is absorbed. They are a source of energy; they provide about 4 Calories (kilocalories) per gram.
Structural polysaccharides are of two main types: chitin and cellulose. 1. Chitin: It is the second most abundant organic substance. Chitin is a complex carbohydrate of heteropolysaccharide type which is found as the structural component of fungal walls and exoskeleton of arthropods. In fungal walls, chitin is often known as fungus cellulose.
What are the four major types of polysaccharides found in nature? ... Amylose, or starch, is a helical chain of Glucose monomers, which are bonded by glycosidic linkages (Alfa linkages 1 - 4). Amylose is a storage polysaccharide in plant cells, we can obtain Amylose from potatoes. ... What are the four major types of polysaccharides found in ...

Lower amounts of carbohydrate are usually associated with unrefined foods, including beans, tubers, rice, and unrefined fruit. Animal-based foods generally have the lowest carbohydrate levels, although milk does contain a high proportion of lactose. Organisms typically cannot metabolize all types of carbohydrate to yield energy.
Polysaccharides. Polysaccharides are very large, high molecular weight biological molecules that are almost pure carbohydrate. They are constructed by animals and plants from simpler, monosaccharide molecules, by joining together large numbers of the simpler molecules using glycosidic bonds (-O-).
A homo-polysaccharide is defined to have only one type of monosaccharide repeating in the chain; whereas, a hetero-polysaccharide is composed of two or more types of monosaccharides. In both types of polysaccharide, the monosaccharide can link in a linear fashion or they can branch out into complex formations.
