Excessive heat may invert dextrose into glucose and fructose.

Explanation:
Inversion refers to breaking the glycosidic bond in a disaccharide like sucrose to produce glucose and fructose. Dextrose is already glucose, so heating it alone won’t produce a mixture of glucose and fructose. You’d need an acid or an enzyme to hydrolyze sucrose to invert sugar, or specific conditions that promote aldose–ketose isomerization (which is not the same as inversion of dextrose). Without those catalysts, excessive heat won’t turn dextrose into glucose plus fructose.
