Worksheet Week #2 Amino Acids and Protein Structure KKD 2009 1) Spell out the secret code below. . 2) As you can tell whoever drew those amino acids doesn’t know anything about pH. Use your pen and show what each amino acid would look like at physiological pH. What would be each NET charge? 3) How many water molecules would you get if you made a peptide out of all amino acids shown? 4) You decide that is too much water (rain) for you and you want to move to CYPRESS. What would that PEPTIDE look like? 5) What is the NET charge of CYPRESS? 6)

Unformatted text preview: What would happen to your peptide under oxidizing conditions? 7) Which of the two peptides absorbs light in the UV range? If both, which one would absorb more light? Why? 8) You realize that this peptide is very cool, because every amino acid can perform a different special task. What are they? 9) Which one of the two peptides is less likely to form an α-helix? Why? 10) What is the dihedral angle around the peptide bond? 11) Draw the structures of His and Trp. Why is His much more likely to be charged at neutral pH than Trp?...
