Amino compounds are widely present in complex mixtures in chemistry, biology, medicine, food, and environmental sciences involving drug impurities and metabolisms of proteins, biogenic amines, neurotransmitters, and pyrimidine in biological systems. Nuclear magnetic resonance (NMR) spectroscopy is an excellent tool for simultaneously identifying and quantifying these in-mixture compounds but has a limit-of-detection (LOD) over several micromolarities (>5 ?M). To break such a sensitivity barrier,...

New 1.2 GHz NMR Spectrometers— New Horizons?
The latest ultrahigh-field NMR spectrometers are a huge technological challenge that require large financial investments. In his Guest Editorial, Harald Schwalbe justifies the need for spectrometers with higher magnetic field strengths. The important results from previous generations of high-field NMR spectrometers are discussed, and research areas are identified that will benefit from the latest spectrometers.

Abstract
O-tert-butyl-tyrosine (Tby) is an unnatural amino acid that can be site-specifically incorporated into proteins using established orthogonal aminoacyl-tRNA synthetase/tRNA...
