does sucrase digest anything else than sucrose, Especially in fruit juices?

If I added sucrase to a fruit juice that contains sugar, would there be any compounds other than the sugar that can be digested by the sucrase?

Sucrase is the name for a collection of enzymes that hydrolize sucrose (table sugar) into fructose and glucose.  The active site of the enzyme is where the actual chemical reaction takes place between a molecule of sucrose and a water molecule.  The active sites of enzymes are extremely specific and are designed to allow only very specific molecules to enter into and interact with the various amino acid side chains to undergo the intended reaction.  In the case of sucrase, only the sucrose molecule can interact in the proper way and by hydrolized.  Other types of sugars such as lactose will not be digested.  Also, other types of chemicals like proteins or fats will not be digested either.  So only the sucrose will be affected.
