INVESTIGATION ON PROTONATION OF N-ACETYL-L-ALANINE BY QUANTUM CHEMICAL CALCULATIONS
VITHAYA RUANGPORNVISUTIABSTRACT: Protonation potentials of N-acetyl-l-alanine molecule were evaluated by means of ab-initio LCAO-MO-SCF calculations. First and second protonation potentials (in gas phase) are -179.4 and -90.7 kcal/mol, respectively. In aqueous solution, only one protonation can take place.
