This study evaluated the effects of caffeic acid and chlorogenic on chemical constituents lychee wine fermented with Saccharomyces cerevisiae DV10 when added at 200 mg/L 300 before fermentation. Results showed that addition had no effect ability alcoholic fermentation S. cerevisiae. The both acids decreased utilization amino nitrogen sources produced less α-ketoglutaric, succinic, acetic acid. ...

The quantitative measurement of amino acids in different areas of the central nervous system has shown that a progressive increase takes place in levels of y-aminobutyric acid during development (2, 3), and that the concentration of this amino acid in adult brain is relatively constant under a variety of physiological stresses. y-Aminobutyric acid is synthesized by glutamic acid decarboxylase, ...

Clarification of the metabolic mechanisms underlying salt stress responses in plants will allow further optimization of crop breeding and cultivation to obtain high yields in saline-alkali land. Here, we characterized 68 differential metabolites of cultivated soybean (Glycine max) and wild soybean (Glycine soja) under neutral-salt and alkali-salt stresses using gas chromatography-mass spectrome...

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...
