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.
