Quiz 1 1. What is the purpose of today’s lab, and how do we do it? - Separating a mixture of two unknown amino acids with different R-groups, using column chromatography on a cation-exchange resin - Visualize cation-exchange separation and identify the two amino acids using thin layer chromatography (TLC) analysis 2. What’s the general structure of an amino acid - Amino group, carboxyl group, R group specific to each amino acid 3. What would bind to an anion-exchange? - Negatively charged amino acid 4. Name the two amino acid isomers - Leucine and Isoleucine 5. Name three positively charged amino acids - Arginine, Lysine, Histidine 6. What is a cation and anion? - Cation: positively charged, more protons than electrons - Anion: negatively charged 7. Label figure 1.3 8.
