Final answer:
The chemical formula for amylose with four glucose units is C24H42O21.
Step-by-step explanation:
The chemical formula for amylose with 4 glucose units is C24H42O21. Amylose is a linear polymer of glucose, consisting of α-D-glucose units linked by α-1,4-glycosidic bonds. One glucose molecule has the formula C6H12O6, and since amylose is unbranched, the formula for four interconnected glucose molecules would be C24H42O21 because each successive glucose molecule loses a water molecule (H2O) upon forming the glycosidic bond with another glucose molecule.
