Cysteine-induced effect on amino acids in neonatal rat brain.
In neonatal rat brain 6 h after s.c. administration of L-cysteine, an increase was observed in most of the amino acids with the exception of glutamic acid, aspartic acid, phenylalanine, sarcosine, glutamine, hydroxyproline and phosphoethanolamine compared to age-matched saline controls. Cysteine was not present at detectable levels in control brain but was found to be 0.38 to 0.52 mumole/g of fresh brain tissue in 2- and 4-day-old rats respectively after cysteine treatment.
