RESEARCH ARTICLE Post-Prandial Protein Handling: You Are What You Just

Background Protein turnover in skeletal muscle tissue is highly responsive to nutrient intake in healthy adults. Objective To provide a comprehensive overview of post-prandial protein handling, ranging from die-tary protein digestion and amino acid absorption, the uptake of dietary protein derived amino acids over the leg, the post-prandial stimulation of muscle protein synthesis rates, to the incorporation of dietary protein derived amino acids in de novomuscle protein. Design 12 healthy young males ingested 20 g intrinsically [1-13C]-phenylalanine labeled protein. In addition, primed continuous L-[ring-2H5]-phenylalanine, L-[ring-2H2]-tyrosine, and L-[1
