is starch a polysaccharide
Polysaccharides are an important class of biological polymers. Their function in living organisms is usually either structure-or storage-related. Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin.In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called 'animal starch'.hey range in structure from linear to highly branched. Examples include storage polysaccharides such as starch and glycogen, and structural polysaccharides such as cellulose and chitin. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit.
