Figure 2.17 Fatty acids. Double bonds in the tails are highlighted in red. A. The tail of stearic acid is fully saturated with hydrogen atoms. B. Linoleic acid, with two double bonds, is unsaturated. The first double bond occurs at the sixth carbon from the end of the tail, so linoleic acid is called an omega-6 fatty acid. Omega-6 and C. omega-3 fatty acids are essential fatty acids, which means your body does not make them and they must come from food. D. The hydrogen atoms around the double bond in oleic acid are on the same side of the tail. Most other naturally occurring unsaturated fatty acids have these cis bonds. E. Hydrogenation creates abundant trans bonds, with hydrogen atoms on opposite sides of the tail. Figure It Out: Are the double bonds in linolenic acid cis or trans?

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. H + 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…
