There is growing recognition that, apart from their role in synthesis of proteins and polypeptides, some amino acids regulate key metabolic pathways necessary for maintenance, growth, reproduction, and immunity. These include arginine, cysteine, glutamine, leucine, proline, taurine, and tryptophan, and are frequently termed functional amino acids. Animal and human clinical research suggests that oral supplementation of these functional amino acids may provide additional health and/or performance benefits under certain conditions or disease states. The following chapter describes some of the food sources and functions of dietary glutamine and taurine, two of the amino acids that may have significant biological function beyond protein synthesis. An overview of the analysis of these amino acids in foodstuffs is also provided.
