Description
Amino acid analysis (AAA) of egg white lysozyme and bovine Achilles tendon collagen was performed using 1H solution-state nuclear magnetic resonance (NMR) spectroscopy. The proteins were hydrolyzed in 6M HCL with and without 0.02% phenol at 110\u00B0C for 24, 48, and 72 hours. For both proteins, 18 of 20 amino acids were characterized including hydroxyproline and hydroxylysine in collagen, using 1-dimensional (1D) and 2-dimensional (2D) NMR spectroscopy experiments. Errors ranging from <1% to 8% were seen in treatments with and without phenol. Both proteins could be correctly identified within their own species using the online database search AACompIdent. The proposed approach is a simple analytical technique that does not require the use of column separation or amino acid derivatization prior to compositional analysis.
