Polysaccharides are complex carbohydrates composed of multiple monosaccharide units linked together by glycosidic bonds. They are classified based on their structure and function.

Types of Polysaccharides

Homopolysaccharides:Composed of a single type of monosaccharide unit (e.g., starch, cellulose)
Heteropolysaccharides:Composed of different types of monosaccharide units (e.g., hemicellulose, pectin)

Structure of Polysaccharides

Linear:Monosaccharide units linked in a straight chain (e.g., cellulose)
Branched:Monosaccharide units linked in a branched chain (e.g., glycogen)
Cyclic:Monosaccharide units linked in a ring structure (e.g., starch)

Functional Roles of Polysaccharides

Energy storage:Starch, glycogen
