5. In Model 1 the original amino acids are combined through a condensation reaction to make the dipeptide. - What does R1 represent in the dipeptide? water 6. Put a box around the atoms in the amino acids that become the H₂O molecule produced by the reaction in Model 1. (Hint: Use models to visualize the reaction.) - What does R2 represent in the dipeptide? Loter 7. A peptide bond is a covalent bond linking two amino acids together in a peptide. Circle the peptide bond in Model 1. Between which two atoms in the dipeptide is the peptide bond located? nitrogen and Carbon Between what two functional groups is the peptide bond located? bonds 8. There are 20 different amino acids found in nature. Two were shown in Model 1. Additional examples are shown below. Write one or two grammatically correct sentences to describe how these amino acids are similar and how they are different. Use the terms R-group, amine group, and carboxyl group in your description. H₂N-C-COOH H Glycine (Gly) They group H CH₂SH H₂N-C-COOH H Cysteine (Cys) H₂C i C NH₂ bnue H₂N-C-COOH H Asparagine (Asn) have the same amino H₂C H₂N-C-COOH H Phenylalanine (Phe) amino grove on Calbayy

3) A 28 yr old woman is newly sober for the past 3 months after completing an intensive outpatient recovery program. She wants to hang out with her co-workers at happy hour in a local club. She is anxious but goes out with them and orders a soda. She feels good that she was able to go out and not have an alcoholic drink. The following week the same scenario plays out without her having an alcoholic beverage. Is she on the path to staying sober or on the road to relapse? Why?
