Question: what is the difference between maltose and trehalose?
Answer: Both trehalose and maltose are disaccharides containing two alpha glucose units. The key difference between trehalose and maltose is that trehalose contains a 1,1-glycosidic linkage, whereas maltose contains a 1,4-glycosidic linkage. Moreover, trehalose is a non-reducing sugar, while maltose is a reducing sugar.
