Interaction of Spin-Labeled Lipid Membranes with Transition Metal Ions
The large values of spin relaxation enhancement (RE) for PC spin-labels in the phospholipid membrane induced by paramagnetic metal salts dissolved in the aqueous phase can be explained by Heisenberg spin exchange due to conformational fluctuations of the nitroxide group as a result of membrane fluidity, flexibility of lipid chains, and, possibly, amphiphilic nature of the nitroxide label. Wheth...
متن کاملSTUDY ON THE COMPLEX FORMATION BETWEEN N-PROPYLSALICYLIDENE BASED ON SILICA AS ION EXCHANGER AND SOME TRANSITION METAL IONS
N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...
متن کاملElectron spin resonance studies of carbonic anhydrase: transition metal ions and spin-labeled sulfonamides.
Electron spin resonance (esr) spectra of Cu(II) and Co(II) carbonic anhydrase, and a spin-labeled sulfonamide complex of the Zn(II) enzyme, are reported. The coordination geometry of Cu(II) bound in the enzyme appears to have approximately axial symmetry. Esr spectra of enzyme complexes with metal-binding anions also show axial symmetry and greater covalency, in the order ethoxzolamide < SH(-) ...
متن کاملDo Ion Channels Spin?
The interior of a living cell is maintained at a different electrical potential than the exterior, by differences in the concentration of various ion species [1]. Changes in this voltage, during action potentials for example, occur via ion flows through specialized pores in the cell membrane. The more rapid the ionic flows through the pores, and the more quickly they can be gated, the more effi...
متن کاملAnisotropy of Doped Transition-Metal Magnets
Calculations of the magnetocrystalline anisotropy are used to evaluate prospects for new lanthanide-free permanent magnets. Based on the requirement of transition-metal-rich phases, we investigate interstitial impurities in tetragonally distorted bcc Fe and sub stitutional impurities in hcp Co, and compare doped bulk materials with nanostructures, especially with elemental 3d and YCo5 nanoparti...
