Metabolite Identification
Common NameL-Galactose
DescriptionL-Galactose (CAS: 15572-79-9) belongs to the class of organic compounds known as hexoses. These are monosaccharides in which the sugar unit is a six-carbon containing moiety. L-Galactose is found in flaxseed. L-Galactose occurs in the polymer agar-agar. Galactose is an optical isomer of glucose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins.
