1. What sorts of residues (i.e. what amino acid side chains) would one expect to find on the surface of a protein with an unusually high isoelectric point (e.g. 9.5). What if the pI were unusually low (e.g. 3.4)? 2. When one talks about “protein-ligand” interactions, what sorts of molecules can be “ligands?” 3. How would you explain the conformational selection model of protein-ligand interactions to an educated lay person?

For the side-chains of the 20 amino acids. Write the 1-letter code and the 3-letter code for each, in groups according to side-chain characteristics (eg. hydrophobic, polar with S or O containing functional groups, and polar with N containing functional groups).  For the amino acids listed, state whether the amino group, the acid group and the side-chain group will be significantly protonated, unprotonated or ~50% protonated at the following pH values: pH= 2.6, 4.8, 6.6, 7.4, 8.4, 9.2, 10.0. Also indicate...
