In the 'MAKE CONNECTIONS' section, it states that fructose is a sweeter-tasting isomer of glucose. Based on the information presented in Figure 5.3 and the related text, what type of isomers are glucose and fructose?

  • A: Enantiomers
  • B: Structural isomers
  • C: Geometric isomers
  • D: Isotopes

Explanation

The text states that glucose is an aldose and fructose is a ketose, both being hexoses C6H12O6 . They share the same molecular formula but differ in the arrangement of their atoms, specifically the location of the carbonyl group at the end for glucose, within the skeleton for fructose . This defines them as structural isomers.
