|Section2= |Section3= }} Levans are a group of fructans; polymers of fructose forming a non-structural carbohydrate, which in the case of levans can themselves link together to form super-molecules comprising even hundreds of thousands. The shortest levan is 6-kestose, essentially a chain of three fructose molecules with a few extra atoms in one segment. Levans are produced in almost all bacterial versions of fructan production, as well as being possible to produce by fracturing soybean mucilage. ==See also== * Food microbiology * Industrial microbiology 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Levan polysaccharide」の詳細全文を読む スポンサード リンク
