H3N-CH-C2 CH-CH3 CH3 Which solution would you predict this amino acid to be least soluble in? (Highlight your answer.) | An aqueous solution at pH 3 • An aqueous solution at pH 6 . An aqueous solution at pH 9 Focus I I E E - age 5 of 5 871 words English (United States)

Answer 1

since the side chain of the amino acid is nonpolar. so the zwitter ion form will be as shown in the figure.

now pI value will be average of coo- group and NH3+ group and is close to ph 6

so at pH near 6 amino acid will have no net charge and hence will be least solube.

so correct option is B
