The increasing order of pKapKa of the following amino acids in aqueous solution is

Glycine, Aspartate, Lysine, Arginine.

The increasing order of pKa of the following amino acids in aqueous solution is Glycine, Aspartate, Lysine, Arginine.The increasing order of pKa of the following amino acids in aqueous solution is Glycine, Aspartate, Lysine, Arginine.

Options

  1. AArginine < Lysine < Glycine < Aspartate
  2. BAspartate < Glycine < Arginine < Lysine
  3. CGlycine < Aspartate < Arginine < Lysine
  4. DAspartate < Glycine < Lysine < Arginine

Correct answer

D. Aspartate < Glycine < Lysine < Arginine

Step-by-step solution

The increasing order of pKa of the following amino acids in aqueous solution is Glycine, Aspartate, Lysine, Arginine.

The increasing order of pKa of the following amino acids in aqueous solution is Glycine, Aspartate, Lysine, Arginine.



Hence, the correct order is
Aspartate < Glycine < Lysine < Arginine.
