Abstract
The kinetic study of decarboxylation of alpha-amino acids has been carried out at various concentrations of ninhydrin at different temperatures (50-80-degrees) and hydrogen ion concentration from 1.0 x 10(-3) to 1.0 x 10(-6) mol dm-3. The reaction follows an irreversible pseudo-first order reaction in presence of excess ninhydrin. The rate of the reaction increases with increase in pH and temperature. On the basis of the observed data a possible mechanism has been proposed.
