Biochemistry 1: Two amino acids have chiral carbons in their side chains (R group). Identify these amino acids and draw the structures of all of the possible stereoisomers of these amino acids. The amino acid with a hydroxyl group is found in proteins with the (2S, 3R) configuration and the other amino acid is found in proteins with the (2S, 3S) configuration. Circle the structures in your answer above that correspond to these isomers.
