Identification
Name: Galactitol
Description:Galactitol, also called dulcitol, is a sugar alcohol, the reduction product of galactose. Galactitol is produced from galactose in a reaction catalyzed by aldose reductase. Galactose itself comes from the metabolism of the disaccharide lactose into glucose and galactose (Wikipedia). It appears as a white crystalline powder with a slight sweet taste.
