In addition, transmitter release, uptake, and metabolism require energy. Since glutamate and its related metabolites are directly associated with the tricarboxylic acid cycle, it might be expected that the metabolic turnover of these amino acids would also reflect the energy needs of the brain....
cysteine, and tyrosine), and are less sensitive to amino acid imbalances and antagonisms. Throughout adulthood, cats and dogs may lose 34% and 21% of their lean body mass, respectively. Adequate intakes of high-quality protein (i.e., 32% and 40% animal protein in diets of aging dogs a...
Meanwhile, amino acid catabolism produces metabolites via deamination and transamination. Glutamine is a rich amino acid in the circulatory system, which can be broken down into glutamate, internalized into the mitochondria, transformed into α-ketoglutarate, thus entering the TCA cycle. TCA is ...

Augmentation of cisplatin’s biochemical and cytotoxic effects by amino acid deprivation suggest that intermittent deprivation of an essential amino acid could allow dose reduction of cisplatin; this could reduce the drug’s side effects, and allow its use in cisplatin-resistant tumors....
Providing many other cellular metabolites to C. elegans also increased longevity suggesting that anaplerosis of tricarboxylic acid (TCA) cycle substrates likely plays a role in lifespan extension. Conclusions Supplementation of C. elegans with 18 of the 20 individual amino acids extended lifespan, but...
食品专业英语 LESSON 4 Amino Acids And Proteins Proteins are molecules of great size, complexity, and diversity. They are the source of dietary amino acids, both essential and nonessential, that are used for growth, maintenance, and the general well-being of man. These macromolecules, characterize...
Amino acid metabolism plays important roles in tumor biology and tumor therapy. Accumulating evidence has shown that amino acids contribute to tumorigenesis and tumor immunity by acting as nutrients, signaling molecules, and could also regulate gene tran
Studies at the molecular level demonstrate that dietary amino acid intake produces substantial effects on health and disease by modulating metabolism. However, how these effects may manifest in human food consumption and dietary patterns is unknown. Here
