ESEEM spectroscopy — probing active site structures of metalloproteinsetic metal centers and free radicals, based on measurement of weak hyperfine interactions. In the two examples provided, Cu(II) and Co(II) coordinated to imidazole, we show how the measurement of nuclear quadrupole and weak nuclear hyperfine interaction provides a basis for understanding how local c

Nitric oxide, a versatile biological ligand for hemeproteiespectral and stereochemical properties of nitrosylhemeproteins and their model nitrosylheme. The structural change in the heme coordination environments on NO binding to hemeproteins is described primarily in relation to the mechanisms of activation and inhibition of the enzymes by NO.

Antioxidant activity of vitamin E and vitamin C derivatives in membrane mimetic systems), 6-laurate (VC-12) and 6-palmitate (VC-16) in micelles and artificial liposomes, aiming to shed light on the effects on the activity of the side-chain of the VCs and the micro-enviroment of the reaction medium. Nitroxides with various lipophilicities, i. e., 4-hydroxy-2,2,6,6-tetramethyl-piperidin

Action of antioxidants as studied by electron spin resonancecussed. The potency for hydrogen atom donation of antioxidants can easily be estimated from the rate of reaction with stable radicals such as galvinoxyl by following the decay of its ESR signal. In general, a potent antioxidant gives a stable radical whose ESR signal gives important information on i

Research on their structure and function is attracting growing attention in the field of biological science, and comprehensive investigations from many fields are helping to understand the real features of these species. In cooperation with this trend, in April 1993 the Yamagata Technopolis Foun

Comparison of In-Depth Case Studies,ion of the frequencies is adjustable, but has a nominal value of 10 kHz, which is much less than the homogeneous linewidth. Successive absorption and emission of photons from both fields by the spin system leads to oscillation of the spin population at k (ω. - ω.) and to the production of intermodul
