Biology XI: 9 Biomolecules (3 Nature of Bonds Linking Monomers)

Nature of Bonds Linking Monomers Nature of Bonds Linking Monomers in a Polymer Peptide Bond Links amino acids in a polypeptide chain This bond is formed when the carboxyl group of one amino acid reacts with the amino group of the next amino acid, with the elimination of water moiety (dehydration). Glycosidic Bond Links two carbon atoms of adjacent monosaccharides to form polysaccharides This also involves dehydration Phosphodiester Bond Links two nucleotides to form nucleic acids This bond is formed between the phosphate and hydroxyl groups of sugar. The phosphate group links the 5’ carbon of one sugar of one nucleotide to the 3’ carbon of one sugar of another nucleotide.
