Question

The increasing order of  of following amino acids in aqueous solution is
Gly, Asp, Lys, Arg

Canvas Classes · Accepted Answer

The  of an amino acid depends on its ionizable side chains. 
- Aspartic Acid (Asp) has an extra carboxyl group, making it highly acidic with the lowest  (around 2.8).
- Glycine (Gly) is a simple neutral amino acid with a  (isoelectric point) around 6.0.
- Lysine (Lys) is basic, containing a primary amine side chain ().
- Arginine (Arg) is the most basic amino acid due to its strongly basic guanidino group ().
Therefore, the increasing order of  is: Asp < Gly < Lys < Arg.
