WebThe amino acid phenylalanine phenylalanine is the has stronger a pKa of 1.83 whereas acid. Hint: Consider the tryptophan has charge pKa of 2.83. Explain in water at pH 7.4. (4 … WebWhen the pH is high and the solution is alkaline or basic, the -NH 2 group of DL-phenylalanine will remain intact and the -COOH group will be deprotonated to form C 6 H 5-CH 2-CH (NH 2)-COO-. As this deprotonated compound at pH 14 contains a negative charge on one of the oxygen atoms, the net charge of DL-phenylalanine at pH 14 will be -1.
