In Chapter 14, we will discuss a class of compounds called amino acids, so named because they contain both an amino group and a carboxyl group. Following is a structural formula for the amino acid alanine.

What would you expect to be the major form of alanine present in aqueous solution (a) at pH 2.0, (b) at pH 5–6, and (c) at pH 11.0? Explain.
