Fig. 9.3 An example of an amino acid. This may be polymerized by a reaction that links two monomers and undergoes the loss of a molecule of water. The process, repeated many times, leads to the formation of long chains that occur in the formation of proteins

The proteins, for their part, are the most complex macromolecules found in living organisms. They are associated with long polymerized chains known as amino acids (Fig. 9.3). Some twenty amino acids are found in living organisms, and it is the sequence of these amino acids that give each protein its function, which may take many different forms.
