Descriptions:
wikipedia: Isomaltulose (trade name Palatinose, chemical name 6-O-α-D-glucopyranosyl-D-fructose) is a disaccharide carbohydrate composed of glucose and fructose. It is naturally present in honey and sugarcane extracts and is also produced industrially from table sugar (sucrose) and used as a sugar alternative. 
It tastes similar to table sugar with half the sweetness. It has the same energy as table sugar, but is digested slower and thus leads to a lower blood glucose and insulin response. In comparison with sucrose and most other carbohydrates, isomaltulose is not a significant substrate for oral bacteria. Consequently, acid production from isomaltulose in the mouth is too slow to promote tooth decay. Its physical properties closely resemble those of sucrose, making it easy to use in existing recipes and processes. 
It is manufactured by enzymatic rearrangement (isomerization) of sucrose from beet sugar. Since the 1950s its physiological role and physical properties have been studied extensively. Isomaltulose  has been used as an alternative to sugar in foods in Japan since 1985, in the EU since 2005, in the US since 2006, and in Australia and New Zealand since 2007, besides other countries worldwide. 
Like sucrose, isomaltulose can be digested to glucose and fructose. However, while in sucrose the glucose is linked to the anomeric carbon of the fructose (an α-1,2 glycosidic linkage), in isomaltulose the linkage is to the 6 carbon (α-1,6), making isomaltulose a reducing sugar, unlike sucrose. The fructose in isomaltulose exists in a ring structure that readily opens  to exhibit a carbonyl group as in ketones and aldehydes, which explains why isomaltulose is a reducing sugar.
Isomaltulose is hydrogenated to produce isomalt, a minimally digestible carbohydrate that is used as a sugar replacer, for example in sugar-free candies and confectionery.
