fructose Fructose, or fruit sugar, is a Ketose, ketonic monosaccharide, simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galacto ...

Fructosyl transferases

In enzymology, enzymes that add a fructose group to a molecule are called ''fructosyl-transferases'', ''beta-D-fructofuranosyl transferases'' or ''fructotranferases''. Examples are: *

aldose beta-D-fructosyltransferase In enzymology, an aldose beta-D-fructosyltransferase () is an enzyme that catalyzes the chemical reaction :alpha-D-aldosyl1 beta-D-fructoside + D-aldose2 \rightleftharpoons D-aldose1 + alpha-D-aldosyl2 beta-D-fructoside Thus, the two substrate ...

Inulin fructotransferase (DFA-I-forming) The enzyme inulin fructotransferase (DFA-I-forming) () catalyzes the following process: :Produces α-D-fructofuranose β-D-fructofuranose 1,2′:2,1′-dianhydride (DFA I) by successively eliminating the diminishing (2→1)-β-D-fructan (inulin) ...

Inulin fructotransferase (DFA-III-forming) The enzyme inulin fructotransferase (DFA-III-forming) () catalyzes the following process: :Produces α-D-fructofuranose β-D-fructofuranose 1,2′:2,3′-dianhydride (DFA III) by successively eliminating the diminishing (2→1)-β-D-fructan (inul ...
