Tracer amino acids can be administered either as a primed-constant infusion or as a bolus. Alternatively, the precursor amino acid can be labeled from orally ingested deuterated water. Ra rate of appearance of the tracee; Rd rate of disappearance of the tracee; FSR fractional synthesis rate; FBR fractional breakdown rate; AAs amino acids.
