Metabolite Identification
Common NameD-Fructofuranose
DescriptionD-Fructose, also known as fruit sugar or levulose, 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. D-Fructose is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, D-fructose participates in a number of enzymatic reactions. In particular, D-fructose can be biosynthesized from sorbitol; which is catalyzed by the enzyme sorbitol dehydrogenase. In addition, D-fructose can be biosynthesized from β-D-fructose 2-phosphate; which is mediated by the enzyme 14 kda phosphohistidine phosphatase. Inulin from dandelion roots has also been used as a source. In humans, D-fructose is involved in fructose intolerance, hereditary. D-Fructose is an odorless tasting compound. Outside of the human body, D-Fructose is found, on average, in the highest concentration within a few different foods, such as honey, agaves, and dates and in a lower concentration in white cabbages, italian sweet red peppers, and tortilla. D-Fructose has also been detected, but not quantified in, several different foods, such as fruit preserves, malus (crab apple), groundcherries, carp breams, and crayfish. This could make D-fructose a potential biomarker for the consumption of these foods. D-Fructose occurs in honey and a large number of fruits, particularly apples and tomatoes. It is fluid and nutrient replenisher, and nutritive sweetener. D-Fructose is also found in many other foods, some of which are sweet cherry, anise, and tinda. Present in polymeric form in the inulins, the energy reserve polysaccharides of many plants, e.g. dahlia and Jerusalem artichoke tubers.
