Skeletal muscle phenylalanine trafficking. A) Intracellular rate of appearance was significantly different between young and older subjects, with a significant effect of time. *P = 0.01 vs. younger group; #P = 0.0005 for time effect. B) Outward transport efficiency was different between young and older subjects, with a significant effect of time. *P = 0.05 vs. younger group; #P = 0.0001 for time effect. C) Synthetic efficiency was higher in young than in older subjects, with a significant effect of time. *P = 0.05 vs. younger group; #P = 0.0001 for time effect.
