WebFor example, at certain pH's, some amino acids will be zwitterionic. Note the diprotic amino acid, Alanine. Alanine has a non-protic side chain (a methyl) , and thus at pH = 7.4 (physiological pH), the carboxyl group has a negative charge (COO-), and the amino group has a positive charge (RNH3+). Therefore, at pH 7.4, L-Ala is zwitterionic. http://www.biology.arizona.edu/biochemistry/problem_sets/aa/Basic.html WebThe charged amino acids at neutral pH (around 7.4) carry a single charge in the side chain.
