SOLVED:A histidine side chain is known to play an important role in the catalytic mechanism of an enzyme; however, it is not clear whether histidine is required in its protonated (charged) or unprotonated (uncharged) state. To answer this question you measure enzyme activity over a range of pH with the results shown in Figure Q 2-1 . Which form of histidine is required for enzyme activity?

SOLVED: BiochemThe amino acid histidine (His) plays an important role in manybiological reactions as part of the protein's active site. The pKafor the protonation of His to form HisH = 6.0.a. When pH = 7.4 (physiological pH), what is the fraction oftotal histidine that will be in the HisH form?b. If the chemical environment shifts the pKa of a histidineresidue from 6.0 to 6.8, what fraction of the histidine residueswill now be in the HisH form?Please show all work.

Ionization State of Histidine Each ionizable group of an amino acid can exist in one of two states, charged or neutral. The electric charge on the functional group is determined by the relationship between its p Ka and the pH of the solution. This relationship is described by the Henderson-Hasselbalch equation. (a) Histidine has three ionizable functional groups. Write the equilibrium equations for its three ionizations and assign the proper p Ka for each ionization. Draw the structure of histid

SOLVED:Imidazole forms part of the structure of the amino acid histidine and can act as both an acid and a base. (a) Look at the electrostatic potential map of imidazole, and identify the most acidic hydrogen atom and the most basic nitrogen atom. (b) Draw structures for the resonance forms of the products that result when imidazole is protonated by an acid and deprotonated by a base.

SOLVED: 2) Calculate the pI of histidine, glutamic acid, and threonine.Draw their corresponding titration curves. Indicate the position ofall pKas and the pI as well as the percentages of each ionic format the start and finish of the titration and at all pKas.3) The activity of an enzyme requires a glutamic acid to displayits â€“COOH functional group in the protonated state. Suppose the pKaof the â€“COOH group is 4.07.a) Will the enzyme be more active at pH 3.5 or 4.5? Explain.b) What fraction o
