Proton magnetic resonance spectra of amino acids.
High resolution nuclear magnetic resonance spectroscopy has already proved its ability to yield valuable information on the structure, reactivity and exchange rate of a variety of compounds. Although its application to substances in aqueous solution has often been limited by solubility and exchange, it has been possible to detect the spectra of several amino acids and dipeptides in water (I). T...
متن کاملProton magnetic resonance spectra or porcine muscle adenylate kinase and substrate complexes.
Porcine muscle adenylate kinase with a molecular weight of 22,000 has 2 histidine, 5 phenylalanine, 7 tyrosine, and no tryptophan residues. The effect of pH, substrate, and the paramagnetic manganous ion on the proton magnetic resonance spectrum of the enzyme, particularly the aromatic region, has been investigated at 220 MHz. The well resolved C2 proton peaks of the 2 histidine residues have b...
متن کاملProton Nuclear Magnetic Resonance Study of Water in Flocs
Polymer/surfactant adsorption can lead to colloidal stability or particle flocculation, both of which are of importance in many industrial processes. Floc structure is one of the most important features of particle flocculation and this involves flOC-size, density and strength.1~ Spectroscopic techniques to investigate floc structure have been mainly limited to small-angle neutron scattering (S...
متن کاملProton nuclear magnetic resonance studies of isonitrile-heme protein complexes.
Steric interactions between bound ligand molecules and the valine E11 methyl groups of human hemoglobin and sperm whale myoglobin have been examined directly by high resolution NMR techniques. The methyl proton resonances of this amino acid are shifted markedly upfield and away from the bulk of the protein resonances by the shielding effect of circulating pi electrons in the porphyrin ring. We ...
