Textbook Question
Chapter 9.6, Problem 1HYEW
The saliva of dogs, like the saliva of most mammals (including humans), contains enzymes, antibacterial compounds, and growth factors. When a dog licks a wound, it not only cleans out some of the dirt and kills some of the bacteria that may have entered, but also leaves growth factors behind. The growth factors speed up the synthesis of cyclins, thereby stimulating the division of cells that regenerate the skin, helping to heal the wound more rapidly.

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.
