Vibrational Dynamics of Poly(L-glutamic acid) (β2 Form)

Determination of Glutamic Acid

Glutamic Acid Dehydrogenase and Glutamic-oxalacetic

As part of a larger project dealing with an in vestigation of amino acid and protein metabolism in leukemia, a study was undertaken to determine those enzymes concerned with amino acid anabo lism and catabolism as they occur in selected tis sues. Several review papers (@,4, 11, 1@)have ade quately summarized our present knowledge of the metabolism of white blood cells (WBC) in leuke mia. Howeve...

Vibrational spectroscopy and DFT calculations of the di-amino acid peptide L-aspartyl-L-glutamic acid in the zwitterionic state.

Solid state IR and Raman as well as aqueous solution state Raman spectra are reported for the linear di-amino acid peptide L-aspartyl-L-glutamic acid (L-Asp-L-Glu); the solution state Raman spectrum has also been obtained for the N,O-deuterated derivative. SCF-DFT calculations at the B3-LYP/cc-pVDZ level established that the structure and vibrational spectra of L-Asp-L-Glu can be interpreted us...

Differential Presentation of Glutamic Acid

Selective Crystallization of Metastable α-Form of L- glutamic Acid through Feedback Concentration Control

Polymorphism is described as the ability of a compound to adopt different crystalline arrangements. Although chemically identical, different polymorphic structures display a variation in its physical properties such as crystal morphology, density, solubility, and color. These in turn exert an influence on the performance of the product; for example, the bioavailability and shelf-life of pharmac...
