Questions  

The bonds present in between amino acids in a polypeptide chain and monomers in a polysaccharide are:

a
Peptide bond and Glycosidic bond respectively
b
Glycosidic bond and peptide bond respectively
c
Ester bond and disulphide bond respectively
d
Peptide bond and phosphodiester bond respectively

detailed solution

Correct option is A

In a polypeptide or a protein, amino acids are linked by a peptide bond which is formed when the carboxyl (-COOH) group of one amino acid reacts with the amino -NH2 group of the next amino acid with the elimination of a water moiety. In a polysaccharide the individual monosaccharides are linked by a glycosidic bond. This bond is also formed by dehydration.
