Plasma arginine and citrulline levels in C57BL and S+S-Antilles mice.

Amino acid analysis of plasma arginine and citrulline levels expressed as the ratio of the amino acid to the glycine level in the same animal. S+S-Antilles mice were either fed regular Purina mouse chow (−) or were supplemented with mouse chow containing 5% arginine (+) in their diet for a 10-week period.
