biological activity | Dulcite is a sugar alcohol with a slightly sweet taste, which is a metabolic breakdown product of galactose. |
uses | is used in microbiology, biochemical research and pharmacy. galactitol (galactitol), derived from galactose, is used to study the mechanism of action of diseases such as cataract formation, hepatosplenomegaly, mental retardation, etc. Galactose is used as a substrate for recognition, differentiation and characterization of galactitol dehydrogenase. a sugar alcohol derived by reduction of galactose is used as a substrate to identify, distinguish and characterize galactitol dehydrogenase. Galactitol can be used as a reference compound in the analysis process for the analysis of sugar alcohols in plants and foods. |
production method | galactose is prepared by reduction of sodium borohydride, separation of ion exchange resin and recrystallization of ethanol. |
