Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Monosaccharide: They are the polyhydroxy aldehydes or ketones containing only one aldehyde or ketone unit. For example: glucose and fructose.

Disaccharide: They are the polyhydroxy aldehydes or ketones containing two aldehyde or ketone units. For example: Sucrose, lactose.

Polysaccharide: They are the polyhydroxy aldehydes or ketones containing more than two aldehyde or ketone units. For example: Cellulose, starch.

Expert Solution

Answer to Problem 17.4E

Cellulose is a polysaccharide.

Explanation of Solution

Cellulose is a polymeric form of D-glucose because cellulose on hydrolysis gives a large number of glucose as monosaccharide. Each glucose is linked with β−1, 4-glycosidic linkage. This type of linkage allows more packed and long chain polymeric structure of cellulose. Therefore, cellulose is an example of polysaccharide.

Conclusion

Cellulose on hydrolysis gives a large number of molecules of glucose. As a result, cellulose is a polysaccharide.
