1. Starch has ?-glucose monomers, whereas cellulose has alternating ?- and ?-glucose monomers.
1. Starch has ?-glucose monomers, whereas cellulose has alternating ?- and ?-glucose monomers.
2. Starch has ?-?-glucose monomers, whereas cellulose has ?-glucose monomers. 3. Starch has alternating ?- and ?-glucose monomers, whereas cellulose has only ?-glucose monomers. 4. Starch has ?-glucose monomers, whereas cellulose has ?-glucose monomers.Explanation / Answer
Starch has alpha glucose monomers and cellulose has beta glucose monomers.
In starch all monomers are in same orientation where as in cellulose every beta glucose monomer is upside down with respect to its neighbor.
So, option D is the correct answer.
