Intravenous infusion of L-glutamic acid results in the augmentation of the cardiac output and an improvement of the circulation in patients with postoperative cardiac failure. This effect is not accompanied by increased myocardial oxygen demand. Arterial plasma glutamate level rises 10-fold and arterial-coronary sinus plasma glutamate difference increases fivefold during intravenous L-glutamic ...

The detecting properties of l-glutamic acid hydrochloride that is deposited on 128◦ YX-LiNbO3 surface acoustic wave (SAW) delay lines are studied in this work. SAW gas sensors that were based on l-glutamic acid hydrochloride had good sensitivity, selectivity, reversibility, and repeatability to ammonia gas. A detection limit of 0.56 ppm for gaseous ammonia was observed when using l-glutamic aci...

Immobilized cell reactor of the bacterium Corynebacterium glutamicum entrapped into carrageenan gel beads was constructed and used for the investigation of batch, fed-batch and continuous production of L-glutamic acid from nutritionally enriched sugarcane molasses. High final L-glutamic acid concentration (>93 g l ) was achieved, in batch fermentation, but with low productivity of 3.8 g l h . R...

L-cysteine–capped Mn-doped ZnS quantum dots (QDs) were used for the determination of glutamic acid in foodstuffs. This method is based on measurement of the quenching of the phosphorescence intensity of the QDs after interacting with glutamic acid. A linear response was observed from 50 to 500 ng mL−1 glutamic acid with a limit of detection of 6.79 ng mL−1 . Room temperature phosphorescence (RT...

The ultimate solution of the problem of cancer will probably involve the recognition of specific chemical differences between the modes of development of normal and of neoplastic cellular tissues. The growth of a tissue comprises the synthesis of protein from the natural amino acids. It has in the past few years become amply clear that all amino acids occurring in proteins have the same “natura...

A mutant of Sfrepfococcus faecalis has been isolated which has a ZO-fold higher growth requirement for L-glutamic acid than the parent strain. The ability to utilize L-glutamine for growth is not affected. The mutant also has a greater dependence than the parent strain on an external supply of vitamin B6. The rate of glutamic acid transport at low extracellular concentrations (0.05 mu) was grea...

We report the synthesis and characterization of high-molecular weight poly(l-glutamic acid) based brush polymers. Utilizing a combination of ring-opening metathesis polymerization of norbornene based monomers and ring-opening polymerization of γ-benzyl-l-glutamate N-carboxyanhydride, high-molecular weight γ-benzyl protected poly(l-glutamic acid) brush polymers are synthesized. Controlled and co...

A combination of neutron diffraction augmented with isotopic substitution and computer modeling using empirical potential structure refinement has been used to extract detailed structural information for L-glutamic acid dissolved in 2 M NaOH solution. This work shows that the tetrahedral hydrogen bonding network in water is severely disrupted by the addition of glutamic acid and NaOH, with the ...

The purification procedure, some properties and the mode of action of glutamic pyruvic transaminase (GPT) from pig heart muscle have been reported in the pre vious papers (1,2). The presence of GPT and glutamic-oxaloacetic transaminase (GOT) activities in the mitochondrial fraction has been reported by Rosewell (3,4), who qualitatively demonstrated the formation of glutamic acid from ƒ¿-ketoglu...
