Polysaccharides
- Polysaccharides are made up of ten or more than ten monosaccharides.
- These are the polymers of monosaccharides.
- These are also called glycans.
- Homopolysaccharides contain only a single type of monomeric unit.
- Heteropolysaccharides contain two or more different kinds of monomeric units
Cellulose:
- In cellulose, glucose monomers are linked in unbranched chains by β 1-4 glycosidic linkages. Because of the way the glucose subunits are joined, every glucose monomer is flipped relative to the next one resulting in a linear, fibrous structure.
- Cellulose is found in the cell walls of plants.
- Cellulose is a fibrous, tough, water-insoluble substance.
- Cellulose constitutes much of the mass of wood, and cotton is almost pure cellulose.
