DL-Glutamic Acid Monohydrate (DL-Glu-OH), 99+%

Glutamic acid is a non-essential amino acid that is also an excitatory amino acid (EAA) because of its role in neurotransmission.1 Its name derives from its historical isolation from wheat gluten. A detailed review of the chemistry of glutamic acid has been published. 2
DL-Glutamic acid has been used as an energy source in the isolation of cultured Thiobacillus acidophilus.3 It has been utilized as a supplement in the diet of chicks and been shown to lead to grown depression.4 DL-Glutamic acid has been utilized as a nitrogen source for the culture of nematode eggs from Arkansas Fungus 18 (ARF18) and Pochonia chlamydospora var. chlamydospora.5
A method for the analysis of DL-glutamic acid and other amino acids via copper(II) ion, hydrogen peroxide, and pyrocathechol violet has been published.6 The resolution of DL-glutamic acid as its acetyl derivative through the use of porcine renal acylase I has been reported.2
DLGlutamic acid has been used as a starting material for the synthesis of imidazo[1,5-a]quinoxaline amides and carbamates that bind with high affinity to the GABAA/benzodiazepine receptor in cultured
