1. My simplified rules for categorizing amino acid by SIDE CHAINS:
A. Has Oxygen
- a.1 if carboxylic acid group => ACIDIC
- a.2 else => POLAR NEUTRAL (amide and alcohol groups)
B. No Oxygen but has Nitrogen => BASIC
C. Has only Carbon and Hydrogen (or just H) => NONPOLAR NEUTRAL
(Don't worry about exception Tryptophan and the two Sulfur containing amino acids. For Mastering Chemistry, just open the Hints or look them up in Table 18.3)
2. I believe there is a mistake in the drawing for MC Question 17 #54. The 6 member ring on the left should have alternating double bonds.
3. Midterm 2 is Wednesday 2/17. Study Guide posted below.
