Carbohydrates are polyhydroxy aldehydes ...

Carbohydrates are polyhydroxy aldehydes or ketones or substances which generally give these upon hydrolysis. These have been classified as mono, oligo or polysaccharides. These are all optically active since they contain number of chiral carbon atoms in their molecules. Further, the carbohydrates may be either reducing or non-reducing in nature. In disaccharides and polysaccharides, the monosaccharides are linked to each other by Glycosidic linkages.
In the polysacharides, the monosaccharides are linked to each other by :

A

Glyosidic Linkage

B

Peptide Linkage

C

Nucleosidic Linkage

D

None is correct

Text Solution

Verified by Experts

The correct Answer is:
A
