This invention is related to a novel sugar-like chemical composition and its use for diabetes therapy. Particularly, the present invention teaches the use of monosaccharide-like glycylated sugar alcohol compounds to block or reduce sugar absorption in diabetes patients, so as to prevent the risk of hyperglycemia symptoms. Glycylation of sugar alcohols is a totally novel reaction that has never been reported before. Therefore, the novelty of the present invention is that for the first time glycylated sugar alcohols not only was found but also was found to be useful for treating Diabetes mellitus. In addition, the present invention teaches a method for producing these glycylated sugar alcohols. In sum, the present invention includes not only a kind of novel sugar-like chemical compositions and its use for treating diabetes but also a state-of-the-art protocol and methodology for producing such a novel composition via glycylation of sugars and sugar alcohols.本發明係關於一新穎似糖化學組成物及其在糖尿病治療上的使用方法。具體而言,本發明教示類單醣之甘胺酸化糖醇化合物的使用,藉以阻礙或降低糖尿病患者對糖的吸收,並且防止高血糖症狀的風險。糖醇的甘胺酸化為先前未曾報導過的新穎反應。因此,本發明不但新發現甘胺酸化糖醇,並且使用該甘胺酸化糖醇治療糖尿病。此外,本發明教示生產該些甘胺酸化糖醇的方法。總括來說,本發明包含一新穎似糖之化學組成物及其在糖尿病治療上的使用方法,並且包含透過糖或糖醇之甘胺酸化生產此新穎組成物之最佳步驟與方法學。MGG‧‧‧單甘胺酸化糖醇DGG‧‧‧雙甘胺酸化糖醇TGG‧‧‧三甘胺酸化糖醇GLUT2‧‧‧葡萄糖轉運子2
