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…
