L-半乳庚酮糖, L-galacto-2-Heptulose

L-Galacto-2-heptulose belongs to the class of organic compounds known as c-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a C-glycosidic bond. L-Galacto-2-heptulose exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Outside of the human body, L-galacto-2-heptulose can be found in cereals and cereal products. This makes L-galacto-2-heptulose a potential biomarker for the consumption of this food product.
