Q. A strongly alkaline solution of a monoaminodicarboxylic acid contains how many basic groups ?

Biomolecules

Solution:

In strongly alkaline solution of an amino acid, all of its $—COOH$ groups are converted into $—COO^{-}$ . Thus a strongly alkaline solution of a monoaminodicarboxylic acid will have one $—NH_{2}$ and two $—COO^{-}$ groups, all of which are basic in nature. Further, $—NH_{2}$ is more basic than a $-COO^{-}$ group.
