Draw aspartic acid (aspartate) at ph 1, ph 7, and ph 13. include hydrogen atoms.

The structures are shown in figure.

Explanation:

At low pH (pH < 1.88) aspartic acid is completely protonated.

Both amine and carboxylic groups are protonated.

At medium pH (3.65-9.68) amine group is protonated and both the carboxylic groups are deprotonated.

At high pH (above 9.68) all the groups are deprotonated.

the millers tale is the answer.
