Invertase is an enzyme that catalyzes the hydrolysis breakdown of sucrose table sugar into fructose and glucose. The resulting mixture of fructose and glucose is called inverted sugar syrup.
Related to invertases are sucrases. Invertases and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose.

Invertases cleave the O-C fructose bond, whereas the sucrases cleave the O-C glucose bond. For industrial use, invertase is usually derived from yeast.
It is also synthesized by bees, which use it to make honey from nectar. Invertase is expensive, so it may be preferable to make fructose from glucose using glucose isomeraseinstead. Chocolate-covered cherries,  other cordials, and fondant candies include invertase, which liquefies the ijvertase.
Once the candy is manufactured, it needs at least a few days to a few weeks in storage so the invertase has time to break down the sucrose. Urea acts as a non-competitive inhibitor of invertase, presumably by breaking the intramolecular hydrogen bonds contributing to the tertiarty structure of the enzyme.
