Is fructose an isomer of glucose or is glucose an isomer of fructose?

Answer:
Yes. And no, that's not an answer from a wise guy. A chemical isomer is a different "version" of a substance that has the same chemical formula but with a different molecular structure, and, therefore, different chemical and physical properties. Both fructose and glucose have C6H12O6 as their chemical formula, and each is an isomer of the other.
