Abstract
Using High Performance Liquid Chromatography(HPLC)to track the transfer-glycoside process all the way.The enzymatic mechanism of α-glucosidase transferring maltose into isomaltose has been discussed.The results showed that in the transformation process,the α-glucosidase cut the α-1,4 glycosidic bonds into two glucose units firstly,then re-bonded by α-1,6 glycosidic linkage.And the isomerization process from maltose to isomaltose finished.The transglycosidation was happened intramolecularly.At the same time,the glucose units which dissociated from maltose reacted intermolecularly with maltose or isomaltose to generate panose or isomaltotriose.关键词
