l-glutamaic acid is the principal excitatory neurotransmitter in the brain and an important intermediate in metabolism. In the present study, lactic acid bacteria (218) were isolated from six different fermented foods as potent sources of glutamic acid producers. The presumptive bacteria were tested for their ability to synthesize glutamic acid. Out of the 35 strains showing this capability, st...

Glutamic Semialdehyde, Synthesis, Reactivity, Glutamic Acid, Derivatives Glutamic-1-semialdehyde which is discussed to be involved in the early steps of chlorophyll biosynthesis, has been synthesized from glutamic acid by reduction of several N-protected carboxylic acid derivatives like the N-CBO-glutamic acid-1-dimethyl amide or methylanilide, the pyroglutamic acid imidazolide and the acid chl...

Wax D(P), a peptido-glycolipid found in extracts of Mycobacterium tuberculosis var. hominis, was not found in extracts of three strains of still-grown M. tuberculosis var. bovis (BCG, Marmorek and Dupray). However, extracts from three other bovine strains (Behring, LA and BB) did yield waxes D(P), and these did not differ as to their molar ratios of alanine/glutamic acid/diaminopimelic acid fro...

In the present study, we identified free amino acid (FAA) contents and chemical composition in four populations of Salmo trutta macrostigma living in Mediterranean region of Turkey. In addition, taste impacts of FAAs were evaluated by taste active values. Moisture, protein, fat and ash content were found in the ranges of 75.49 - 79.59 %, 16.94 - 19.97 %, 1.58 - 3.75 % and, 1.39 - 1.56 %, respec...

Weil-Mahlherbe (1) reported in 1936 that glutamic acid is the only amino acid which can be absorbed and assimilated in the brain. Since that time there has been developed the clinical application of glutamic acid to brain diseases. For instance, it is reported that the glutamic acid intravenously infused can relieve or cure hypogly cemic coma (2) ; when administered orally, it shows a striking ...

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...

99mTc-Labeled annexin V has been used for the imaging of tumor apoptosis induced by chemotherapy. However, owing to the short half-life of annexin V, multiple injections of the radiotracer are necessary to capture the peak apoptotic activity. In this study, we evaluated the imaging properties of an 111Inlabeled, long-circulating annexin V. Methods: Both polyethylene glycol (PEG) and the metal c...
