Answer:
Polysaccharides, also known as glycans, are the polymers of carbohydrate. These polymers are composed of the monosaccharide monomeric units that are joined together by glycosidic bonds.
A polysaccharide molecule composed of the same type of monosaccharide units is known as homopolysaccharide or homoglycan.
Example: Cellulose, glycogen, and cellulose.
Whereas, a polysaccharide molecule composed of more than type of monosaccharide is known as heteropolysaccharides or heteroglycans.
Examples: Hyaluronic acid and heparin
