The bond formed when the carboxyl (-COOH) group of one amino acid reacts with the amino (-NH2) group of the next amino acid is

In a polysaccharide the individual monosaccharides are linked by a glycosidic bond. This bond is formed by dehydration. This bond is formed between two carbon atoms of two adjacent monosaccharides.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.Phosphodiester bond is formed between two nucleotides in a polynucleotide chain.
