Metabolite Identification
Common NameD-Tagatose
DescriptionD-Fructose, also known as D-tagatose or D-lyxo-2-hexulose, belongs to the class of organic compounds known as monosaccharides. Monosaccharides are compounds containing one carbohydrate unit not glycosidically linked to another such unit, and no set of two or more glycosidically linked carbohydrate units. Monosaccharides have the general formula CnH2nOn. D-Fructose exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. D-Fructose exists in all living species, ranging from bacteria to humans. D-Fructose participates in a number of enzymatic reactions, within cattle. In particular, D-Fructose can be biosynthesized from sorbitol through its interaction with the enzyme sorbitol dehydrogenase. In addition, D-Fructose can be biosynthesized from Beta-D-fructose 2-phosphate through the action of the enzyme 14 kda phosphohistidine phosphatase. In cattle, D-fructose is involved in the metabolic pathway called the fructose and mannose degradation pathway. D-Fructose is a potentially toxic compound.
