Answer:
Step-by-step explanation:
In basic solution (pH = 11), an amino acid typically exists in its zwitterionic form. This means that the amino acid has both a positive and a negative charge, due to the presence of both a basic amino group (-NH2) and an acidic carboxyl group (-COOH).
The structure of an amino acid in basic solution (pH = 11) can be represented as follows:
The central carbon atom (also known as the alpha carbon) is bonded to a hydrogen atom, an amino group (-NH2), a carboxyl group (-COOH), and a side chain R group.
The amino group is positively charged due to the loss of a proton (H+).
The carboxyl group is negatively charged due to the gain of a proton (H+).
Overall, the amino acid has a net charge of zero, due to the equal and opposite charges of the amino and carboxyl groups. This is known as the zwitterionic form of the amino acid.
Here is a visual representation of the structure of an amino acid in basic solution (pH = 11):
