Answer: Peptide bond
Explanation:
Polysacharride are monomers of carbohydrates linked together by glycosidic bonds to form long chains, also proteins are polymers of amino acids linked together by peptide bonds.
Linear chains of carbohydrates are linked together by glycosidic alpha-1,4- glycosidic linkages(between the OH group of the first carbon if the 1st monomer and the OH group of the 4th carbon of the second monomer. The branched point are linked by alpha-1,6-linkages.
In proteins the alpha carboxyl group of one amino acid react with alpha amino group of another amino acid to form a peptide bond or CO-NH bridge. Proteins are made by polymerization of amino acids through peptide bonds.
