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

Text Solution

Verified by Experts

Monosaccharides units present in strach, cellulose and glucose can be determined by knowing the product of their hydrolysis.
(i) Strach is a polysaccharide of `alpha`-glucose in which two types of linkage are observed i.e., `C_(1)-C_(6)` and `C_(1)-C_(4)` glycosidic linkage
(ii) Cellulose is a straight chain polysaccharide of `beta-D` glucose in which glucose are linked together by `C_(1)-C_(4)` glycosidic linkage.
(iii) Glucose is a monosaccharide.

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 ?
