Metabolite Identification
Common Namebeta-D-Galactose
DescriptionGalactose is an optical isomer of glucose. An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Galactose is less sweet than glucose and not very water-soluble. Galactose is a monosaccharide constituent, together with glucose, of the disaccharide lactose. Galactose is produced by hydrolysis of lactose by galactosidase. This enzyme is produced by the lac operon in Escherichia coli (E. coli). Galactan is a polymer of the sugar galactose. It is found in hemicellulose and can be converted to galactose by hydrolysis.
