Glutamine 94-103 complement component 3 Mus musculus 128-132 7760058-6 1995 From the C-3/C-4 labeling ratios in glutamine and glutamate and from the corresponding C-3/C-2 labeling ratio in GABA obtained with [2-13C]acetate, it was concluded that the carbon skeleton of glutamine to some extent was passed through TCA cycles before glutamate and GABA were formed. Glutamine 193-202 complement component 3 Mus musculus 87-90
