Fig. 8.5. The pathway of enzymatic synthesis of fructo-oligosaccharides in onion
bulbs. The enzymes indicated are: SST, Sucrose:sucrose 1-fructosyl transferase;
1-FFT, fructan:fructan 1-fructosyl transferase; 6G-FFT, fructan:fructan 6 G -fructosyl
transferase. Alternative and more explicit names for kestose and neokestose
mentioned near the top of the diagram are 1 F -fructosyl sucrose and 6 G -fructosyl
sucrose, respectively (from Fujishima et al ., 2005. Courtesy of New Phytologist © ,
