Outcome Measures
Primary Outcomes (1)
Plasma amino acid concentrations as measured by High Performance Liquid Chromatography (HPLC)
Plasma samples will be drawn at times 0, 30, 60, 120, 180, 240, and 300 minutes after the consumption of the trial meal. The amino acids that will be assessed are alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine.
