Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together.
