what type of a bond links amino acids to one another?
The covalent bond between amino acids is called a peptide bond. It is really an amide bond, so letâs look at amide bonds first. In organic chemistry, a carboxylic acid reacts with an amine in a so-called condensation reaction to form an amide plus water. R(C=O)-OH + H-NRâ â R(C=O)-NRâ + HâO. carboxylic acid + amine â amide.
