In how many groups does polysaccharide dassified?



Polysaccharides are dassified into two groups :
(a) Homopolysaccharides or Homoglycans : These are formed by polymerisation of only one type of monosaccharide monomers. For e.g., starch, glycogen, cellulose are composed of a single type of monosaccharide called glucose.
(b) Heteropolysaccharide or Heteroglycans: These are
produced by condensation of two or more types of monosaccharide derivatives. They indude agar, peptidoglycan, arabanoxylans etc
