Difference between Amylose and Amylopectin

Amylose is a glucose polymer with long chain-like molecules, while amylopectin consists of larger highly branched molecules (1 to 6).

Amylose

  • It is a linear polymer of a-glucose.
  • It is water-soluble.
  • It constitutes about 10-20% of the starch.
  • It forms blue color with iodine.
  • It has 60-300 glucose units.
  • It forms by C1 – C4 glycosidic linkage.
  • Soluble in hot water but does not form starch gel ot paste.

Amylopectin

  • It is a branched chain polymer of a-glucose.
  • It is water-insoluble.
  • It constitutes about 90-80% of the starch.
  • It forms red colour with iodine.
  • It has 300-600 glucose units.
  • It forms by C1 – C6 glycosidic linkage.
  • Soluble in hot water with awelling.
