Identification
Name:Sorbitol
DescriptionSorbitol, also known as glucitol, is a sugar alcohol. It is obtained by reduction of glucose changing the aldehyde group to an additional hydroxyl group. Sorbitol is a polyhydric alcohol with about half the sweetness of sucrose. It occurs naturally and is also produced synthetically from glucose.
