B..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.
