Example Sentences:

	1.	Fos contain mixture of gf2 , gf3 and gf4 sugars ( where g = glucose molecule and f = fructose molecule ) and a dp ( “ degree of polymerization ” ) of 3 - 5 ( “ neosugar ” ) , are not naturally - occurring but are enzymatically synthetized from sucrose by action of an enzyme from the fungus aspergillus niger 详细说明：是以蔗糖做底物，采用呋喃果糖苷酶转果糖基作用，在蔗糖分子上以（ 1 2 ）糖苷键上与1 - 3个果糖分子结合，形成的蔗果三糖（ gf2 ） 、蔗果四糖（ gf3 ） 、蔗果五糖（ gf4 ）属于果糖和蔗糖构成的直链杂低聚糖，在形成的产物中还有果糖、葡萄糖和未反应完全的底物蔗糖，采用色谱法除去单糖和双糖制得高纯度的低聚果糖。
