Answer:
both are sugars, disacharids but it composition is quite different. As their uses.
Step-by-step explanation:
sucrose is made by glucose and fructose, is used to sweet food. Is a non reducing sugar.
maltose is made by malt and glucose, it is used to prepare alcohol beverages. The join of the monosacharides is an alpha glycosidic join. Maltose also is reducing sugar.
They can not present isomerism because they need to have different arrangements but the same atoms, and since this molecules have different monosacharids is not possible to rearrange atoms.
