Difference between starch and cellulose on basis of their chemical properties and structure
| Starch | Cellulose |
|---|---|
| It is a polymer of α-D-Glucose. | It is a polymer of β-D-Glucose. |
| Starch is a branched polymer of liner polysaccharide amylase and a highly branched polysaccharide amylopectin. | Cellulose is a polymer of glucose units. It is long and unbranched. |
| Starch shows α-1, 4 linkages. | Cellulose forms β-1, 4 linkages. |
| Starch has general form of grains. | Cellulose has general form of fibres. |
| Starch is soluble in water when heated. | Cellulose is insoluble in water. |
