Fructopyranose is the free form of fructose. When fructose is attached to another glucose forming sucrose or attached to other fructose making fructans, it does so in its furanose form.
When invertase breaks down sucrose into glucose and fructose, the furanose form of fructose that occurs in sucrose, is now a pyranose form that can be metabolized in the liver by fructolysis.

They are isomers. Both of them have the same molecular formula ($\ce{C6H12O6}$) but different structures.
