IN 1939, it was suggested by one of us 1 that the amide-nitrogen of glutamine was a source of urea-nitrogen and that urea formation was paralleled by a continuous re-synthesis of glutamine.

Mammalian cells fuel their growth and proliferation through the catabolism of two main substrates: glucose and glutamine. Most of the remaining metabolites taken up by proliferating cells are not ...

“As GBM, like most malignant cancers, is dependent on fermentation for energy synthesis and survival, the simultaneous restriction of fermentable fuels, such as glucose and glutamine, while elevating ...

They discovered a significant decrease in two types of tRNA: the initiator methionine tRNA, essential for starting protein ...

Muscle uptake of this increased ammonia load results in the formation of glutamine. Whereas release and recirculation of glutamine will result in the regeneration of ammonia, splanchnic generation ...

Amino acid metabolism involves the synthesis, breakdown ... For example, the amino acid L-DOPA is used to treat Parkinson's disease, while L-glutamine supplementation is being investigated for its ...
