Amino acids, principally alanine and perhaps glutamine, represent the most important sources of de novo carbon available for glucose production. Skeletal muscle is the predominant site of amino acEXCEL 发表于 2025-3-25 19:37:30

In recent years increasing evidence pointed to the probability that glutamic acid also functions as an excitatory neurotransmitter in the central nervous syst牛的细微差别 发表于 2025-3-25 23:13:05

Enzymology of Glutamineal nervous system for removal of ammonia and of glutamate, a neurotransmitter. Glutamine is a major energy source in kidney , small intestine , bone , and in certain cells grown in tissue culture [5,6J. Hydrolysis of glutamine by renal glutaminase plays a key role in acid-base balance. Glut拱墙 发表于 2025-3-26 06:12:02
Metabolism of Vascular and Luminal Glutamine by Intestinal Mucosa in Vivo, showing that glutamine was vigorously oxidized to C0. by incubated ileal tissue from several laboratory animal species, appears to be the first reported indication that glutamine may be a preferred substrate for intestine. These studies seem to have attracted little attention, however, perhapscomely 发表于 2025-3-26 12:15:13
Renal Glutamine Metabolism and Hydrogen Ion Homeostasiserves; acidosis due to nonvolatile acid production is termed metabolic acidosis. During uncontrolled diabetes the incomplete oxidation of fats accelerates nonvolatile acid production inducing life threatening metabolic acidosis. In both physiological and clinical circumstances cellular H. homeostasi真实的你 发表于 2025-3-26 12:38:17
Effects of 2-Oxoglutarate and Glutamate on Glutamine Metabolism by Rat Kidney Mitochondria enzyme for 2-oxoglutarate was decreased at acid pH values. Moreover, additional studies from our laboratory demonstrated that renal glutamine metabolism was accelerated by hydrogen ions in the presence, but not in the absence, of 2-oxoglutarate, suggesting an important role for this metabolite in trecession 发表于 2025-3-26 16:58:46
Role of Fatty Acids in Simultaneous Regulation of Flux Through Glutaminase and Glutamine Synthetase 76, Burch et al. 1978a). Thus, in the species whose kidney contains both glutaminase and glutamine synthetase, the possibility exists that renal degradation and synthesis of glutamine occur simultaneously.
