The L-aspartateβ-decarboxylase ofPseudomonasdacunhaehas high optical specificity and acts only on L-aspartic acid. Thus, when DL-aspartic acid is used as a substrate in theenzyme reactionusing immobilizedP.dacunhaecells, D-aspartic acid and L-alanine are produced at the same time. Both produ...
The racemization half-lives (i.e., the time required to reach a D/L = 0.33) at pH 6.8 for aspartic acid and phenylalanine in the sweetener aspartame (L-aspartyl-L-phenylalanine methyl ester) were determined to be 13 and 23 hours, respectively, at 100 degrees C. Racemization at this pH...

The aspartylation constants are maximal in the acid range and approach zero at pH larger than 6. The data show that deamination is due to the attack of a proton from the phosphate groups. If the proton is ionized or is substituted by an organic radical no deamination takes place. A ...
A biomolecule-assisted hydrothermal route to the fabrication of magnetite (Fe3O4) with uniform microsized and regular octahedral morphology has been successfully developed by use of toxic-free aspartic acid as reducing reagent and FeCl3·6H2O as iron source. The as-prepared magnetite was characterized...
