- Q: Compare And Contrast The Structure Of Collagen And Cellulose
The monomer of collagen is an amino acid whereas the monomer of cellulose is beta-glucose. The monomers in collagen are linked by peptide bonds whereas those of cellulose are beta (1,4)-glycosidic bonds. Collagen is an alpha helix polypeptide with a turn...

Comparison between Starch, Glycogen and Cellulose
Comparison between Starch, Glycogen and Cellulose
| Characters | Starch | Glycogen | Cellulose |
| Monomer | a-glucose | a-glucose | b-glucose |
| Type of bond between monomers | 1,4 glycosidic bond (amylose) + 1,4 and 1,6 glycosidic bond (amylopectin) | 1,4 and 1,6 glycosidic bonds | 1,4 glycosidic bond |
| Nature of chain | Amylose is coiled unbranched Amylopectin is long branched chains, some coiling | Short many branched chains, some coiling | Straight, long unbranched chains form H-bonds, with adjacent chains |
| Occurrence | In plants | In animals and fungi | In plants |
| Function | Carbohydrate energy store | Carbohydrate energy store | Structural |
| General form | Grains | Small granules | Fibres |
