It needs to be converted into glucose in the first place. This takes time and it’s the cause of lower glycemic index.

Glucose is digested very rapidly, since it can be used up by the cells directly. Fructose first has to be processed by the liver, where it’s turned into glucose, and then into fat if it’s not used up elsewhere. That means eating frucose won’t raise the blood sugar immediately.
