2.4.1.9 | sucrose + (2,1-beta-D-fructosyl)n |
FTase possesses only transfructosylating activity, acts on sucrose by cleaving the beta-1,2 linkage and transferring the fructosyl group to an acceptor molecule such as sucrose and fructooligosaccharides, releasing D-glucose |

2.4.1.9 | sucrose + [(beta-D-Fruf-(2-1))n]-alpha-D-Glup |
fructoologosaccharides are synthesized from sucrose at the expense of fructose residues from inulin and related polysaccharides. Fructose residues are transferred from polysaccharide to sucrose molecules, forming a trisaccharide in the first instance. Further fructose residues might then be transferred to the trisaccharide, yielding a tetrasaccharide, and so on. No significant reaction with sucrose alone |
