Fructoside
Fructosides are glycosides that contain fructose. They are abundant in living organisms, food, and the environment. This makes them a particular interest in pharmacology and food science. C1 of fructose may be bonded to any organic moiety, forming a fructoside. The configuration of the fructoside can be denoted as an α-fructosidase or β-fructosidase depending on whether the organic moiety is bonded below or above the plane of fructose, respectively. The naming of fructoside-related enzymes also follows this nomenclature.
