Subunits form larger organic molecules. Two glucose molecules are linked together through dehydration synthesis, which involves the removal of a water molecule. The resulting disaccharide can be represented as shown below.
The diagram on the right represents an amino acid, which is the monomer of proteins:
Please circle the amino group, put a square around the R group, and place a rectangle around the acid (carboxyl) group.
The structure of a dipeptide is shown below. This molecule can be split into two amino acids through hydrolysis. Please circle the atoms of the two amino acids that were once part of the water molecule.
