That's not metabolically true. Fructose by definition doesn't have glucose which is present in sucrose. Metabolically, your body absolutely reacts differently.
A core issue is that isolated fructose and its derivatives, e.g. HFCS, don't sufficiently trigger satiety. In contrast, regular sugar and glucose trigger satiety. This has been known for over a decade:
