Starch and Cellulose

Similarities

  • Unstable
  • Form condensation reactions
  • Polysaccharides
  • Formed from glucose
  • Contain glycosidic bonds

Differences

  • Starch (Amylose):-
  • Storage of glucose
  • Alpha Glucose
  • Coiled/ compact
  • Tensile strength
  • Digestable
  • Cellulose:-
  • Structural
  • Beta glucose
  • Strand/ straight
  • High tensile strength
  • Indigestable

Overall comparison

In conclusion, Starch and Cellulose have many similarities for example - they both originate from glucose. However- Starch originates from Alpha glucose and Cellulose is from Beta Glucose.
