Hilt First Midterm Score (100): ___________ Equations: pH = pK a + log {[b]/[a]} (K a ) (K b ) = 1 x 10 -14 pH = - log [H + ] F = (q 1 q 2 ) / ε r 2 K b = x 2 / (y-x) G = H - T S K a = x 2 /(y - x) pH = (pK a 1 + pK a 2 )/2 Amino acid pK a ’s: α -amino group (9.6); α -carboxyl group (2.1) side chains: D (3.9) E (4.2) H (6.0) K (10.5) C (8.3) R (12.5) Y (10.1) Oligopeptide pK a ’s: N-terminal amino group (7.4); C-terminal carboxyl group (3.6) 1. (8 pts.) One of the amino acids has two amino groups in it. Draw its complete structure, in the form that would predominate at pH 10, in the space below. 2. The following oligopeptide is drawn: ( 8 pts.) a) Give the one-letter code for each amino acid in the sequence:_________________________ (8 pts.) b) For the above peptide structure to be drawn as the predominant form, the pH of the solution must be somewhere between pH ____ and pH ____.
