D-Galactose CAS 59-23-4

D-Galactose is a white crystalline powder, about 30% as sweet as sucrose, naturally occurring in dairy products and plant polysaccharides.It is mainly used as a food additive (low-calorie sweetener), pharmaceutical raw material (e.g. diagnostic reagent) and a component of culture media, and its metabolic pathway is related to lactase deficiency.Needs to be stored against moisture and avoid high temperature caking.
