Exercise A: Amino Acid Functional Groups
Figure 1 below shows one of the 20 amino acids that make up proteins. Recall that
carbon can form four covalent bonds. Amino acids consist of a central carbon, called
the a-carbon, that is bonded to four different chemical groups.

CH2
OH
Figure 1. Structure of an amino acid
Answer the below questions in your own document.
• On the amino acid shown in Figure 1, label the a-carbon.
• The a-carbon of each of the 20 amino acids is bonded to one hydrogen
atom, one amino group, one carboxyl group, and one R group (more on
that below). You should recognize the amino and carboxyl groups from our
discussion of functional groups in organic molecules. Circle and label* the
amino group and the carboxyl group in Figure 1.
*Note: our goal in this question, and in similar questions throughout this lab, is for
you to be able to identify specific structures. You can do this circling/labeling in
whatever way is easiest for you. You might want to draw the…

3. The 1952 Miller-Urey experiment involved heating water, methane, ammonia, and
hydrogen in sealed, interconnected glass vials. The purpose of this experiment was to
simulate the conditions and substances on early Earth before life. Heating these
simple substances led to the formation of 23 simple amino acids in one week. Amino
acids can be linked together into long, complex molecules that cells need to carry out
the basic life functions. What can be determined by analyzing the data produced by
the Miller-Urey experiment?
