• structures
  • Using CS-CHEMeleon, Δδ predicted versus experimentally determined secondary structures were compared for large datasets of membrane and non-membrane proteins as a function of RCCS dataset, Δδ threshold, nucleus, localized parameter averaging and secondary structure type. (springer.com)
  • The study explores in vitro by circular dichroism and mass spectrometry the effects of pH, Cu+2 ions and sheetbreakers on the secondary structures and self-aggregation of b-amyloid peptides [A�43, A�42 and Abof Alzheimer's disease. (ebscohost.com)

  • Chemical
  • Isomerism , the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties. (britannica.com)
  • bonds
  • Although the distinction is not always clear-cut, since certain bonds that are formally single bonds actually have double bond character that becomes apparent only when secondary resonance contributors are considered, like the C-N bonds of amides, for instance. (wikipedia.org)
  • alpha
  • Proline is the only proteinogenic amino acid with a secondary amine, in that the alpha-amino group is attached directly to the side chain, making the α carbon a direct substituent of the side chain. (wikipedia.org)
