Kinetics studies on thermal isomerization of β-N-oxalyl-L-α,β- diaminopropionic acid by capillary zone electrophoresis

The reciprocal thermal isomerization in aqueous solution between neurotoxic nonprotein amino acid β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) in seeds of Lathyrus sativus (LS; grass pea) and its nontoxic isomer α-N-oxalyl-L-α,β-diaminopropionic acid (α-ODAP) was studied using capillary zone electrophoresis (CZE) in the range from pH = 2.5 to pH = 13 at T = 75 °C, and a decrease of the equilibrium concentration ratio of α-ODAP with the increase of pH of the solution was found. In the range of temperatures 55-95 °C. The rate constants have been measured and thermodynamic parameters such as activation energy (E(a)) and the pre- exponential factor (A) have been calculated.

Thermal isomerization of the neurotoxin β-N-oxalyl-L-α,β-diam inopropion ic acid

The rate constants and reaction order for the conversion of the neurotoxin β-ODAP to α-ODAP have been determined, after off-line thermal treatment, using the recently developed flow injection system for the neurotoxin based on a glutamate oxidase reactor. The effects of the initial concentration of the toxin, temperature and pH on the kinetics and the equilibrium of the endothermic process were examined. The conversion followed a zero order rate law. The reaction rate at pH 7 increased by about two-fold for every 10°temperature rise. The rate at pH 2 was about 60% higher than at pH 7.
