Question

are shown below. Describe how the fully protonated and fully deprotonated r from the image I have provided (pH7). Alternatively, you can draw your answer 2. Two different amino acids are shown b MSWord or by hand. Be sure to draw olutamic Acid: pka(cooHj-2.10, pka(NH.)-9.47; pka(side chain)-4.07 Fully Protonated (pHspKa for all ionizable side groups; 0.25pts): COO CH Fully deprotonated (pH>pKa of all ionizable side groups; 0.25pts) CH 2 COo b. Isoleucine: pKa (COOH)-2.32; pKa(NH2)-9.76 Fully Protonated (pHkpKa for all ionizable side groups; 0.25pts): "H3N-?-??? CH-CH CH 2 CH Fully deprotonated (pHopKa of all ionizable side groups; 0.25pts)s:

Explanation / Answer

I am going to tell you in short and you can draw the whole diagram. The answers are in sequential manner.

A) Protonated = Change both COO- to COOH

A) Deprotonated = Do not change the COO- but change the NH3+ to simple NH2

B) Protonated = Again change COO- to COOH

B) Deprotonated = Change NH3+ to NH2
