Types of polysaccharides on the basis of functionality, Biology

FUNCTIONALLY POLYSACCHARIDES ARE OF THREE TYPES - Storage, Structural, Mucopolysaccharides

Storage polysaccharides function as reserve food which can be hydrolyzed to form sugars required for respiration and biosynthesis, e.g., starch, glycogen, insulin.
Structural polysaccharides are fibrous polysaccharides that are employed in the formation of cell walls of plants, fungi, and exoskeleton of arthropods, e.g., cellulose, fungus cellulose and chitin.
Mucopolysaccharides are slime and mucilage producing polysaccharides, e.g., hyaluronic acid, keratan sulphate, chondroitin sulphate, phycocolloids, pectins, etc.
