QUESTION 03 - Regarding the amino acid arginine, answer the following questions: (Data: pka NH₂ Lyd NH NH₂ Arginina HN2 (-COOH) =2,17;pka (-NH3)=9,04;pka OH =12.48) Explain using resonance structures why, when the arginine side chain isprotonated nitrogen, from the guanidino group, which a double bond is the one that accepts the proton. a) Discuss why the form in which arginine was written would not be found in solution, considering opH=physiological (7,3).
