In zwitter ionic form, amino acids show amphoteric behaviour as they react both with acids and bases.
Except glycine, all other naturally occurring \(\alpha\) - amino acids are optically active, since the \(\alpha\) -carbon atom is asymmetric. These exist both in 'D' and 'L' forms. Most naturally occurring amino acids have L-configuration. L-Aminoacids are represented by writing the \(-NH_2\) group on left hand side.
Optically inactive amino acid from the following is :CUET 2023 Medium - The rate constant, activation energy and the Arrhenius parameter at \(27^{\circ} C\) are \(2.0 \times 10^{-5} s^{-1}, 100 kJ mol ^{-1}\) and \(6.0 \times 10^{14} s^{-1}\) respectively.
