Exercise A: Amino Acid Functional GroupsFigure 1 below shows one of the 20 amino acids that make up proteins. Recall thatcarbon can form four covalent bonds. Amino acids consist of a central carbon, calledthe a-carbon, that is bonded to four different chemical groups.H+CH2OHFigure 1. Structure of an amino acidAnswer 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 hydrogenatom, one amino group, one carboxyl group, and one R group (more onthat below). You should recognize the amino and carboxyl groups from ourdiscussion of functional groups in organic molecules. Circle and label* theamino group and the carboxyl group in Figure 1.*Note: our goal in this question, and in similar questions throughout this lab, is foryou to be able to identify specific structures. You can do this circling/labeling inwhatever way is easiest for you. You might want to draw the structures on a piece ofpaper, or use a computer program (like Powerpoint, Photoshop, Paint, Preview, etc.)to draw on these images. Whatever is easiest for you!• The last bond an a-carbon in an amino acid makes is to an R group.or side-chain. Circle and label the R group in Figure 1.The next page of this handout shows the structures of all 20 amino acids (Figure 2).They are categorized into 4 chemical groups: nonpolar, uncharged polar, acidic, andbasic.• Using the three groups you identified in Figure 1 as a reference, what is the onlything that is different about each of the 20 amino acids?Look at the amino acids in each of the four groups and compare them to the ones inthe other groups. Figure out rules that describe what the members of each groupScreenshot The next page of this handout shows the structures of all 20 amino acids (Figure 2).They are categorized into 4 chemical groups: nonpolar, uncharged polar, acidic, andbasic.• Using the three groups you identified in Figure 1 as a reference, what is the onlything that is different about each of the 20 amino acids?Look at the amino acids in each of the four groups and compare them to the ones inthe other groups. Figure out rules that describe what the members of each grouphave in common so that you will be able to identify the chemical group for each ofthe 20 amino acids if you are shown its structure.
