Question
Which of these statement is NOT true about amino acids?
Answer: Option D
:
D
Amino acids contain an alkali amine group and an acidic carboxyl group, both of which exists in the ionic form in solutions. The caboxyl group loses a proton, which is taken up by the amine group. Therefore amino acids contain both positive and negative ion, forming a zwitter ion. Diffraction studies reveal that amino acids also exist as zwitter ions in the solid state.
