Fructan

A fructan is a polymer of fructose molecules. Fructans with a short chain length are known as fructooligosaccharides. Fructans can be found in over 12% of the angiosperms including both monocots and dicots^[1] such as agave, artichokes, asparagus, leeks, garlic, onions (including spring onions), yacón, jícama, barley and wheat.

Fructans also appear in grass, with dietary implications for horses and other grazing animals (Equidae).
