Polysaccharides: The basic formula is ( C6H10O5)n . These are macromolecules capable of acting as structural or storage molecules.
Storage Polysaccharides: Starch is a plant storage polysaccharide that is composed entirely of glucose joined by @1-4 glycoside linkages. amylose is the simplest form of starch. amylopectin is more complex and is branched. Glycogen is an animal starch stored in the liver and muscles of vertebrates. It is more highly branched than amylopectin.
Structural Polysaccharides: Cellulose and chitin are examples of structural polysaccharides.
Cellulose is the most abundant organic compound on earth. It is made of glucose, like starch, but they differ in the type of 1-4 linkage. Instead of an @ linkage as in starch cellulose contains a B 1-4 linkage.
This causes the polysaccharide to take on a step arrangement and not a linear one like in starch.
Enzymes find it difficult to brake the B 1-4 linkage.

all three are long chains of glucose (but hooked up differently), Humans can break down glycogen and starch but not cellulose.
