The two monosaccharides are joined together by an oxide linkage formed by the loss of a water molecule. Such a linkage between two monosaccharide units through oxygen atom is called glycosidic linkage. In disaccharides, if the reducing groups of monosaccharides i.e., aldehydic or ketonic groups are bonded, these are non-reducing sugars, e.g., sucrose. On the other hand, sugars in which these functional groups are free, are called reducing sugars, for example, maltose and lactose. A non reducing disaccharide 'A on hydrolysis with dilute acid gives an equimolar mixture of D-(+)glucose and D-(+)-Fructose. Glucose on reaction with acetic acid gives glucose pentaacetate. What does it suggest about the structure of glucose ?
