Textbook Question
Chapter 35.3, Problem 1CSC
Stomach acid can be very destructive to the digestive tracts of people with bulimia, many of whom vomit several times daily. The strong acid in the stomach contents dissolves the protective enamel of teeth, making them extremely prone to decay. Stomach acid also damages tissues of the gums, throat, and esophagus. In extreme cases, the explosive pressure of repeated vomiting can tear or rupture the esophagus—a true medical emergency. Frequent vomiting weakens the stomach lining, allowing acid to attack the stomach wall, which may produce ulcers, and can even cause the stomach to rupture, a situation that can be fatal.
During normal digestion, food moves from the stomach to the small intestine—how is it processed there?

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.
