1. (a) Draw the structure of L-glutamic acid and show its one letter and three letter code. (1 pt) (b) Show the calculation for its isoelectric point. (HINT: Check the pKa of the R group also.) (2 pt) (c) Draw the forms of glutamic acid at pH 1, 6 and 10. (3 pt) (d) To which electrode would glutamic acid migrate in electrophoresis at pH 7 buffer, the anode (+) or cathode (-)? (1 pt) (e) MSG (monosodium glutamate) is...
Note that the pKa of gamma-carboxyl group of glutamic acid is: 4.3. Calculate the pH at which the gamma-carboxyl group of glutamic acid is 3/5 dissociated. What is the concentration of [H^+] in solution at this pH? Show your calculations to receive full credits.
Draw an approximation for the titration curve of glutamic acid which is the non-ionized or protonated form of glutamate. Make sure to label the axis. Clearly label each pKa on the graph (Hint: it may help you to connect the pK to the x and y axis, but not required). What is the Isoelectric point? Define the term isoelectric point, calculate and label the point on the graph. Draw the major species of glutamic acid with appropriate formal charges at...
Draw the structure of glutamic acid at physiological pH, 7.4
at a ph below the pka, will the acid be protonated, deprotonated, or the same amount? and what charge will it have?
What is the predominant form of pyruvic acid (pKa =2.50) and lactic acid (pKa = 3.86) at physiological pH (7.4)? Draw the predominant structure of each. In which amino acid does the R group bond to the amino group?
The activity of an enzyme requires a glutamic acid to display its −COOH functional group in the protonated state. Suppose the pKa of the −COOH group is 4.07. At what pH will the enzyme show 82% of maximal activity?
Draw the structure of a 3-mer containing leucine, histidine, and glutamic acid in the ionic form that predominates at pH 7. Please explain all the steps and so I can read it :)
