Which monosaccharide units are present in strach, cellulose and glucose and which linkage link these units?

Text Solution

Verified by Experts

All these polysaccharides are made up of glucose units. In starch and glycogen. `alpha`-glycosidic linkages are presnet while in cellulose , `beta`-glycosidic linkages are present between glucose units.

The space in which atoms are not present in unit cell is

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 ?
