The kestose or fructan series of sucrose-related oligosaccharides is found in at least 12% of vascular plant species [23]. Kestoses contain one glucose moiety per oligosaccharide chain, derived from the parent sucrose molecule by the action of fmctosyltransferases. The simplest kestose, monofructosyl-sucrose is a trisaccharide that exists as three isomers 1-kestose (l - 8-D-fructofuranosylsucrose), 6-kestose (6 - -D-fructofuranosylsucrose), and neo-kestose (6 - -D-fructofuranosylsucrose). These isomers form the basis of three major kestose subseries with different linkage patterns [23]. 

Fructans are oligomers and polymers formed by polymerizing fructose from transport metabolite sucrose on one out of three possible starter trioses 1-kestose yields inulin-type (2 1)-p-D-fructans, 6-kestose yields levan-type (2 6)-p-D-fructans (Fig. 3A), and neo-kes-tose yields mixcD-type and/or branched (2 1), (2 6)-p-D-fructans (Fig. 3C). Pronounced fructan metabolism is found in composites (chicory, Jerusalem artichoke), Liliaceae (onion, chives, garlic), cereals (wheat, barley, rye, oat), Asparagaceae (asparagus), Amaryllidaceae (banana), and Agavaceae (agave).
