The optical active amino acid salt may be a pure mono component, a mixture with it and a salt of racemic modification, namely, a so-called low-quality optical active salt, or a mixture of it and one or more amino acid salts. A wide range of amino acid salts can be racemized ...
DL-Aspartic acid (DL-Asp) is a racemic mixture of the proteinogenic amino acid L-aspartate and the non-proteinogenic amino acid D-aspartate. DL-Aspartic acid is used in studies on factors and conditions that enhance semen and sperm quality. DL-Aspartic acid is used to develop and assess ...

He showed that what had been thought to be a pure substance (racemic acid) was a mixture of two compounds: the natural, dextrorotatory tartaric acid and a substance that, although identical to the first compound identified in all of its other chemical properties, was yet opposite in its ...
DL-AP5 Sodium salt is the sodium salt of(Cat. No. 0105) and a racemic mixture of the D- and L-isomers of AP5, a selective NMDA receptor antagonist that competes with glutamate binding and is commonly used to inhibit NMDA-dependent synaptic plasticity.(Cat. No. 0106) is the more activ...

Racemic 5-Hydroxyvalproic Acid Sodium Salt information, including chemical properties, structure, melting point, boiling point, density, formula, molecular weight, uses, prices, suppliers, SDS and more, available at Chemicalbook.
The racemic erythro-(+/-)-(E)-3,5-dihydroxy-7-[3'-(4"-fluorophenyl)-1'-(1"methylethyl )indol-2'-yl]hept-6-enoic acid may both be resolved into two optically pure enantiomers, the 3R, 5S and 3S, 5R isomers by chromatography on silica gel column using organic solutions as the elu...
Glufosinate is a racemic mixture of D- and L-phosphinothricin. L-Phosphinothricin is a naturally-occurring bacterial amino acid that irreversibly inhibits glutamine synthetase (GS), resulting in death in green plants. The ammonium salt of glufosinate is widely known as phosphinothricin, or PPT, and...
