- b. Please draw the structure of the polypeptide: threonine-lysine-glutamine-valine at pH 7.0, and identify the alpha carbons. C. Estimate the isoelectric point of the polypeptide in (b.)?Previous Assignment: The figure below shows the bonding of the cytosine and guanine molecules. The O - H and H - N distances are each 0.110 nm. In this case, assume that the bonding is due only to the forces along the O - H - O, N - H - N and O - H - N combinations, and assume also that these three combinations are parallel to each other. Calculate the net force that cytosine exerts on guanine due to the preceding three combinations. Is this force attractive or repulsive? ---------------------------------------------------------------------------------- Electric Potential Energy: Base Pairing in DNA, IICalculate the electric potential energy of the guanine–cytosine bond, using the same combinations of molecules (O - H - O, N - H - N and O - H - N) as in the previous assignment (pls refer above)Titration curve of an unknown amino acid The graph below shows a curve, which was obtained following titration of an unknown amino acid. Include a suitable descriptive title stating the identity of the unknown amino acid Use rectangles to precisely outline the regions in the graph where ionisable groups show buffering activity (base/acid ratio 1:10 to base/acid ratio 10:1); clearly associate the name of the ionisable group with the buffering regions; indicate within the graph all observable titration mid-points and all observable titration end-points and indicate estimates of the pKa of the three functional groups (do not provide pka values from the literature, you need to read the pka from the titration curve provided). Note that it is not possible to estimate the pka with more than one decimal precision due to limited resolution of the shown graph.
