XI BIO- Example of HOMOPOLYSACCHARIDES- CELLULOSE,INULIN,GLYCOGEN,STARCH-SUMIT CHOUHAN TUTORIALS IN THIS VIDEO CLASS XI SUBJECT-BIOLOGY CHAPTER 9 BIOMOLECULE Starch, glucose, and glycogen are examples of typical homopolysaccharides. Starch is mostly produced by green plants to store energy. Since starch is that type of polysaccharides, which is made up of the only same type of sugar monomer or monosaccharides, that is why it is also called homopolysaccharides. Chitin- a fibrous substance consisting of polysaccharides, which is the major constituent in the exoskeleton of arthropods and the cell walls of fungi. Q.Starch gives blue colour with iodine, but not cellulose Ans.Starch forms helical secondary structures which can hold iodine, but cellulose does not contain helices, and so cannot hold iodine
