Inulins are polymers mainly comprised of fructose units and typically have a
terminal glucose. The fructose units in inulins are joined by a beta-(2-1)
glycosidic link. Plant inulins generally contain between 2 to 140 fructose
units. The simplest type of inulin is 1-kestose, which has 2 fructose units
and 1 glucose unit.
Inulins with a terminal glucose are known as
alpha-D-glucopyranosyl-[beta-D-fructofuranosyl](n-1)-D-fructofuranosides,
abbreviated as GpyFn. Inulins without glucose are
beta-D-fructopyranosyl-[D-fructofuranosyl](n-1)-D-fructofuranosides,
abbreviated as FpyFn where n is the number of fructose residues and py is the
abbreviation for pyranosyl.
Hydrolysis of inulins may yield oligofructose, which are polymers with a
degree of polymerization (DP) of <= 10

所以他單體有果糖也有葡萄糖 但是以果糖為主 所以歸類成fructan類
