متن کاملCloning and functional characterization of a fructan 1-exohydrolase (1-FEH) in edible burdock (Arctium lappa L.)
BACKGROUND We have previously reported on the variation of total fructooligosaccharides (FOS), total inulooligosaccharides (IOS) and inulin in the roots of burdock stored at different temperatures. During storage at 0°C, an increase of FOS as a result of the hydrolysis of inulin was observed. Moreover, we suggested that an increase of IOS would likely be due to the synthesis of the IOS by fruct...
متن کاملA Novel Fructan Possessing DB Value from Roots of Arctium lappa L
A fructan named ALF was isolated from the roots of Arctium lappa L.. The structure of ALF was identified by analyses of methylation, GC-MS, and both 1 H and 13 C NMR spectroscopy. The results obtained indicated that ALF, comprised of D-fructose and D-glucose in the molar ratio of 14:1, was an inulin-type fructan, which was confirmed by the composition of 14 fructose residues linked by (2 1) gly...
