Example sentences
  • This is important because according to the theory of site-directed dichroism at least three dichroic ratios have to be known to determine the main structural parameters of the helix.
  • The analyses of circular dichroism and fluorescence spectroscopy suggest that the monomer is well folded, and that it has certain characteristic features when compared to its tetrameric counterpart.
  • This result is consistent with a recent investigation of K3 in the presence of large unilamellar vesicles of anionic phospholipids by circular dichroism spectroscopy in the solution state.
